Last summer I built a camera trap with one goal in mind – photograph bears in their environments without people. I’m fascinated the insights you can gain into the animals and initially imagined all sorts of dramatic, National Geographic worthy photography. In short, I was convinced that “EPIC!” imagery was a guarantee. While I’m not there yet, I did manage to capture some dramatic moments, some fun ones, and learned a little about managing a camera trap along the way.
For humans there is a lot of ways to “skin a cat”, for bears there is a lot of ways to catch a salmon. Throughout my images I saw bears perch above to look down in pools, snorkel in pools, and charge up pools. I’m sure each of these techniques had their strengths and their weakness.
Family interactions was something I hoped to gather more of. These two cubs with their mother were a special treat with an extra story. I deployed this camera and then walked back to my vehicle along the river and watched with my telephoto lens. About 10 minutes later this mother and cubs strolled down the river and then got spooked by something in the woods – likely a larger bear. They sprinted down river a ways and remarkably went right past my camera trap. Apparently the sow was not too concerned with the larger bear as she permitted her cub to capture a fish.
Bears are very active at dusk and dawn. Next year I’ll be operating a camera with a flash to better capture these bears in the low-light hours. I learned quickly to program my motion trigger to only take images during the daylight hours as to avoid wasting battery on night shots. I do like the context and silhouette of this bear as it strolls in the evening, however
Bears are curious animals and I knew that could pose a risk to my camera. I housed my camera in an ammo can and that sufficed to keep the bears from wrecking it. There were some funny moments when the bears had to get a closer look though! One time a bear tried to eat the camera and another it walked straight up to the camera to smell it and fogged the glass. Photography can be risky business for your gear as I found out in this separate anecdote that always makes me chuckle.
Moments in the River
There were many, many images of bears being bears. Strolling up river, being observant, smelling out salmon and being gregarious. These are those moments and I challenge you to learn what you can from them.
Looking to Next Year
I simply cannot wait to continue to watch bears through my camera traps! This coming season I’m expanding my arsenal to two camera traps with upgraded capabilities. Two cameras will allow me to diversify my shots and provide new angles. I’m hoping to answer some questions such as “How do bears use hot feet” and “how to do bears use scratch poles” among others. Keep your eyes posted! You can always follow on Instagram or Facebook for the latest content.
No season has it’s markers like Spring. The “first of spring” events which mark our regions are cherished by those who live there and bring joy, warmth, fresh sounds, and fresh colors. Since living in Hoonah, Alaska for four years no spring event has taught me more about a place, its people, and myself than the annual herring egg distribution every April. These small eggs, laid by silvery fish are at the center of culture and politics, science and business, and celebration and uncertainty.
Rain showers had been passing through during the morning of April 9th, and there was obvious relief from the growing crowd when they stopped only minutes before the “Shirley N” came into sight and made its way to Hoonah’s dock. For the last week the Shirley N had been in Sitka, Alaska laying branches of Hemlock in the water. Spawning herring had deposited their eggs on the branches and the Shirley N was bringing them to Hoonah’s expectant crowds. Audible joy and utters started as soon as the first load came from hold of the ship. It had been an abundant year thanks to the skill of the crew and there would be plenty for all! The branches were thick with spawn and each laden bow brought new smiles as they were stashed away. The atmosphere of the day is the primary reason I make sure never to miss the Shirley N’s return.
I have been meaning to write this article since April 9th – it’s now July 14th. I’m honestly glad I waited 3 months before completing this entry. It has changed my focus and intent completely. After reviewing my images I noticed one thing : all of the smiling faces. These are not “fake smiles” for a watching photographer. Rather, they are smiles from both youth and adults which are truly happy to be in that place at that time. Each smile shows someone enjoying the beautiful day, abundant harvest, anticipation of fresh food, and celebration of culture. These smiles capture the true feeling of the day and embody what it means to be in Hoonah : celebrating seasons and fresh food from the ocean. This is my fourth time participating in the eggs coming in, and I look forward to it more eagerly each time because of the emotions it brings out of Hoonah!
What’s So Good About Them?
If you have not had Herring Eggs before this article would be very hard to relate to. You may be thinking “what’s so good about them?”, “what do they taste like?”, and “how do you use them?”. I’ll do my best to help you understand, but I hope you have a chance to try them yourself someday! Simply learning to enjoy them and prepare them has taught me so much about Hoonah and their importance in culture.
Herring eggs are simply good for you. They are salty and fresh and depending on whether they are on kelp or branches have a totally different taste. The kelp adds a saltier, earthier taste while the tang of citrus is wonderful from the branches. They are half protein, a quarter carbs, and a quarter fat. You cannot beat that! Those stats are a key reason they were relied on by coastal peoples since time immemorial.
Herring Eggs are eaten fresh, par-boiled from the branches, pickled, canned, frozen, and eaten on herring egg salads. Their consumption in the spring is important but so is their use in the autumn during “pay off parties”. These parties are celebrations thanking family members and the opposite clan in town for taking care of funeral arrangements and costs for elders who have passed in the year. No payoff party would be complete without herring eggs.
The fate of the herring fishery is unknown. Its future lays in between the politics of the state and tribes, firmly wedged between the interests of the commercial sac-roe industry and needs of subsistence harvesters. If that doesn’t seem complicated enough, all of those factors are only exacerbated by ocean change driven by climate change. Struggling herring runs which have traditionally fed communities for hundreds of years have created enormous tension between communities, tribes, commercials industry, and the state fishery managers. Newspaper headlines of “Tribes sue state” are juxtaposed against “Harvest quota unchanged” and highlight the integral problem in this issue : subsistence fishers feel the commercial industry is highly impacting herring, however state management has been unmoving in how their models determine sustainable yield. This is despite harvests falling short of quota (due to lack of fish) in 2018, 2016, 2013, 2012, and no commercial sac-roe harvest in 2019.
For me the issue and cut and dried. These fish and their delivery to Hoonah has taught me the importance of fighting for small communities in big issues. It has demonstrated to me first hand how bad science can trickle down to dramatic effects. Collapsing herring stocks hurt communities, fisheries, whales, and entire ecosystems. I will stand in solidarity and protest with the Tribes and communities impacted by the extortion and extraction of this resource by outside interests.
It is unknown what 2020 will bring for Herring. There will be more legal battles and (with some optimism) hopefully change to sustainably manage this culturally and ecologically important resource. I look eagerly forward to it knowing it will welcome in yet another spring and another opportunity to enjoy what the season can offer.
When I think of the American Pine Marten (Martes americana), it invokes an image of giant, rotund spruces and hemlocks in an old growth forest. In my mind, the lithe body of a Pine Marten scurries around in the branches perhaps a hundred feet from the forest floor in search of a red squirrel or bird’s nest. A small squeak indicates that the small mustelid has connected with its prey. This vision could be considered “classic” in the fact that martens are strongly associated with mature, old growth forests (Greg 1995). In fact, their dependence on old growth forests is so strong that traditional logging methods have been cited as a driver of large scale declines of marten populations (Davies 1983). In some regions of Southeast Alaska marten are still abundant, and in general the Tongass National Forest offers great habitat for marten. However, they are most often found on the mainland, and I was told by a friend that they were introduced to Chichagof Island by people. That tidbit of information intrigued me, and as I dove into Pine Marten history on Chichagof I was very interested to find out a marten I crossed paths with is a descendant from a small introduction of intentional transplants.
Transplanting wildlife to new areas in Alaska has been going on since the Russians began to settle here (Paul 2009). Frequently transplants happened on the Aleutian Islands or the islands of Southeast Alaska and often the incentive revolved around economic opportunity. A well-known example of this is the transplant of Blue Fox to the Aleutians so they could be farmed and harvested for trapping. The fox were responsible for extirpating several species of birds from the islands. Over the years many species including Caribou, Sitka Blacktail, Mountain Goats and Elk have been introduced to new areas throughout Alaska. The first martens were introduced to Chichagof Island in 1949 to create a population for trapping (in fact Pine Martens are still Alaska’s largest fur market earning 1-2 million annually (Alaska Department of Fish and Game)). By 1954, 21 marten had been introduced to the Island and despite the low number of starting individuals, their numbers climbed rapidly in their new environment. It is estimated in 2006 over 2,200 marten were trapped on Chichagof Island. It’s a remarkably successful population here!
Since transplants can have negative effects on resident populations, did the transplant of marten to Chichagof Island impact populations there? Anecdotally I have been told that Dusky Grouse (Dendragapus obscurus) numbers have declined on the island and that Northern Flying Squirrel (Glaucomys sabrinus) are not as abundant as they used to be. Certainly each of these prey items are consumed by the martens. Buskirk (1983) found birds and squirrels made up a strong majority of the marten’s diet in Southcentral Alaska, but that voles, mice, and shrews were the most important items in the diet. On Chichagof Island, the diet patterns are the same, although Ben-David et al. (1997) found high variation in the autumn and the presence of salmon and crab. In the summer a marten’s diet may be made up 80% of birds and squirrels. Marten populations are normally not very large and hence would be unlikely to strongly influence prey, but Chichagof Island holds the highest abundance in the region (Flynn and Ben-David 2004). With these high populations and a diet favoring birds and squirrels, is it is possible that marten populations on Chichagof Island exert a top-down pressure on their prey? I believe based on the effect of being a successful transplant makes it it possible. However, I can find no data on the population trends of Dusky Grouse or Flying Squirrels on Chichagof Island and there are many other factors at play. For instance, Dusky Grouse may find protection from predators in old growth and flying squirrels are likely to benefit from old growth structure. Hence, removal of old growth by logging may lead to a reduced population. Rather than conjecture on a speculative answer, I will put it out there that a graduate student and the Alaska Department of Fish and Game could pair up on this venture.

I will leave you with a description of my encounter with an American Pine Marten. On October 16th, Hoonah received measurable snow before Fairbanks, Alaska. The 14 inches of snow that lay on the ground was the first time Southeast Alaska had beat the Interior to snow in over 70 years. I started up my truck, my wife jumped in, and we headed out the road with the hope of photographing a bear in the snow. The lower elevations were slick and wet. 6 inches of slush lay heavy on the roads, but we made it the 10 miles to the turn towards False Bay. As we slowly climbed the pass the truck seemed to shrink into the ground as the snow levels rose. After only a couple of miles we were plowing snow with the bumper of the truck and it was evident that we would not go much further. The only catch was we could not find a place to turn around. On we drove hoping that our luck held out, when up the road we saw a small figure bound into the ditch. It plowed into a snow drift and then burst back out again. In a flash I was out with my camera clicking away. Pursing my lips I made small rodent sounds which intrigued the inquisitive creature. Turning its head rapidly it dove back into a snow bank and emerged a few feet away. To me it seemed as if the little fellow was simply enjoying the snow rather than doing anything too serious. He wove in and out of cover, posed for me and eventually bounded into the woods in search of greener (or whiter) pastures.

For the last 2.5 years in fulfillment of my Masters in Wildlife Biology at the University of Alaska Fairbanks, I have been researching the biological and human component of two key moose hunters (wolves and humans) within the Yukon Flats. I am happy to say that the full thesis is is completed and that I will be graduating in December! In my eyes, a critical next step is to make the results of this work public. Hence, I will be dedicating four blog entries to the subject. This first installment will introduce the biology of the region, study area, and my research questions. My next installment will examine access of subsistence hunters to moose within the region. Following that I will look at movement of wolves in the region, and I will conclude by looking at areas were the likelihood of competition between wolves and humans for moose is highest.
I conducted my research on human hunters and wolves in the Yukon Flats, Alaska. The predator-prey relations in Yukon Flats are unique because wolves and subsistence users pursue low-density moose that are held at a low-density equilibrium from predation. In fact, moose are at some of the lowest densities in the world (<0.20 moose per square kilometer).
Broadly I was interested in:
How do human hunters and wolves utilize their environment when pursuing moose?
How does understanding space use and movement and of humans and wolves pursuing moose help us understand competition for a scarce resource they rely on?
The Yukon Flats National Wildlife Refuge is located in central Alaska, and extends nearly 220 miles east to west and 120 miles north to south. It falls directly into a the boreal forest, which means if you walk around that you’ll find birch, black spruce, white spruce, alder and willow. Its namesake is the Yukon River which bisects the Flats, and the huge watershed of the Yukon River is fed by a plethora of rivers. In short, it is a water dominated system.
Within the Yukon Flats there are several communities that are defined by their reliance on the land to harvest food, fuel, and fiber. Their subsistence lifestyle provides up to 85% of the resources they use including but not limited to moose, fish, and waterfowl. Since moose are such low densities but are critical for humans and moose, it is interesting to research how moose are pursued, and where the likelihood of competition between humans and wolves in the highest. Answering any of those questions pertinent for managers. My thesis integrated spatially explicit (i.e., locations) datasets of moose (Alces alces) hunters and of wolves (Canis lupus) to ultimately evaluate how two predators pursue a common resource, moose.
To this end, Chapter 1 of my thesis will be the second installment on this blog and focus on quantifying rural hunter access in the Yukon Flats, Alaska, through spatially-linked interviews. I chose this research topic because previous studies have only qualitatively surmised use area for subsistence resources by drawing boundaries around use areas. However, a quantitative approach can yield firmer management information. My novel approach provided pertinent insight into resource use for our system and created a method that may be applied to other systems. Using results generated from subsistence hunter interviews, I applied a model of access to moose hunting areas. Harvest reporting is low among the subsistence communities in our study, and from our results we generated an estimate of harvest based on game densities similar to the best data available on reported harvest. As such, my method may provide an alternative to, or supplement, harvest-ticket reporting.
In Chapter 2, I characterized movement paths (i.e., hunt paths) between moose kills by six packs in the Yukon Flats. The results of that work will be the third installment on this blog. The movements of wolves have been studied and documented in many high prey-density systems, but almost no information exists on their movements when prey is just dense (<0.20 /km2) enough for wolves to survive.
Finally, I will tie what I learned about wolf movement and human access to examine where competition between humans is the most likely. At that time, I hope to provide a full copy of the thesis for comprehensive reading of the research. I look forward to sharing this information with you, please feel free to ask questions!
Last night I did it again, and I enjoyed every minute of it. Yup, when I bring someone out for their first aurora and they are so excited that they can barely stand, I share in that excitement. Their grin is my grin and their joy is my passion. Their exuberance was warranted, as the aurora put on a beautiful show for us over the dogyards of Black Spruce Dog Sledding and for Alaskans across the state. It was hard not pull up one of the empty sleds that beckoned to the watcher to layback, relax, smile, and enjoy the show. It truly is a beautiful world.

The 18+ foot tides of Homer Alaska define life on the seashore. Its consistency and rhythm are the drumbeat of the ocean. During the summer each day, salmon return to the “Fishing Hole” with the incoming and outgoing tide chasing schools of baitfish, only to be chased by fisherman. Shorebirds feed at the tideline and in the exposed rocks which contain many insects and invertebrates in the crevices. Tide pools contained trapped wonders to because observed with curiosity, and which have evolved to survive the temporarily dry conditions. They often closing up, or shrinking under the sand to conserve water. My time in Homer, Alaska was focused around the seashore, fishing, beach combing, birding, and peering into tide pools. These pictures and experiences are both through my lens, and Kassie’s too.
Peer into a tidepool, and what shall you see? Small creatures, shells, or an anemone.
As the tide goes out, large boulders hold water and sea creatures – tide pool!
The tentacles of a green anenome reach for the surface in a a tide pool.
This large, lone, mussel displays one of its unique characterists. The strong, hair fibers of its holdfast which secure it to a a rock.
Within a tidepool I watched this tiny hermit crab discover, and then attempt to pry loose this limpet for dinner. For scale, this tiny limpet is half the size of a dime, and the crab even smaller.
This particular anenome in the tide pool was very striking. Wedged between two rocks, I was able to capture it through the surface of the water!
(1) The sand flats in between the rocks may holder larger treasures….
(2)… like this starfish! This large star fish was 10 – 12 inches across. We moved it to a wetter, and safer tide pool.
This image of a dead clam among the rocks, and surrounded in seaweed seemed to imbibe the whole concept of tidal change to me.
As we walked along the beach a northwestern crow began to dig a hole along the surf line. To our astonishment it jerked out a thin, silvery, and wriggling Sandlance from the bottom of the hole. Hopping forward a bit further the crow did it again, and again. Other crows were doing the same thing, and were apparently highly efficient hunters. I relayed this video (below) to a birding group, and was informed this hunting behavior may be specific to Homer crows. Have a watch, and let me know your guesses on how they locate the eels. I have not a clue!
You never know what you will see when you leave Seward Harbor, but with blue skies and calm seas our hopes were high for a remarkable trip. Our trip last year on this same boat, and captained by the same crew had been truly memorable!
We reached the open ocean at the edge of Resurrection Bay about 20 miles outside of Seward harbor, and immediately recognized based on an enormous flock of gulls and sea-birds that something special was happening in front of us. Of course, the many tails of humpback whales emerging from the water was a good tip too! As we carefully approached the scene the captain explained that we were observing “bubble-net feeding” of a large group (~18) humpback whales. This behavior has only been recorded consistently around Seward for about five years, as apparently many of the whales had taught it to each other. Observing from the water surface, it is hard to imagine the underwater pandemonium of bubble-net feeding. In the deep waters under a large school of bait fish all 18 whales were blowing bubbles in synchrony to herd the bait ball into one group. Once corralled, all of the whales ascended to the surface with their huge mouths agape to scoop up as many fish as possible. From the surface we were able to predict the timing and location of each emergence, because the flock of hundreds of seabirds would lift up high into the sky, before diving on the susceptible fish just before the whales broke the surface!
Our boat drifted silently with the engines turned off, and as the whales came up for the fifth time under the baitfish the flock of tell-tale gulls began to fly straight towards our boat! It was going to be a close encounter!! Sure enough, enormous mouths attached to up to 80,000 pounds and 80 feet of whale broke through the surface near the boat in a show that left me shaking. Not from fear, but rather sheer awe-struck wonder. I simultaneously snapped imagery of the incredible scene and watched each wonder unfold. I was too busy taking imagery to record video of the whales breaking the surface, but have chained together a series of images in the video below that demonstrate the behavior of bubble-net feeding. Be sure to listen to the incredible sounds they make while on the surface!
The humpback whales were just the start of a remarkable series of wildlife sightings. A first of my life was the killer whales. A large pod of them traveled along and breached frequently for air exposing their fin and distinct white eyepatch. The dominant male of the group was evident thanks to an especially large dorsal fin. Baby orcas surfaced directly behind their mothers as they were still dependent them for protection, and to learn from. We spotted many sea otters throughout Ressurection Bay and along the coast. The story of their recovery is remarkable. Sea otters were extirpated from much of their traditional range by exploiting Russian and American hunters. Their loss led to the collapse of kelp beds as urchins populations, a diet item of the sea otter, expanded and ate of the kelp hold fasts (their roots). Once protected by federal law, the recolonization of sea otters helped reestablish the kelp communities and repair a crucial underwater ecosystem for small fish, and many invertebrates.
This sea otter was found cracking a clam in the Seward Harbor before we departed.
Sea otters are iconic creatures of the Resurrection Bay.
The enormous mouth of a mature humpback whale opens as it breaches the surface.
A humpback whale finishes it ascent through the baitfish school by breaking the surface, mouth agape. The gulls all around were waiting for the scrambled fish.
This humpback whale showed off a spurt of energy in a triumphant jump into the air. A full breach!
We were not the only boat watching the feeding frenzy. This image puts into perspective the size of the fluke!
As we moved further out of Resurrection Bay we encountered a pod of Killer Whales! The dominant male was demarcated by a large fin and led the pod.
The progress of the killer whales was quick, and water splashed from their fins as they breached for air.
Near northwestern glacier harbor seals use icebergs as resting haul-outs and to raise pups.
A large group of harbor seals shares a flow of ice.
A large flow of ice holds several harbor seals and is set against the foggy islands of the distant Chiswell Islands.
During the day we found several groups of stellar sealions – the groups of composed of one dominant male and the much smaller females. These two females rested on a rock ledge shrouded in fog.
The Chiswell Islands provide important breeding habitat and refugia for many sea birds. Puffins, murres, kittiwakes, and dozens of other species are found throughout their rocky crags where they escape predation risk. Many of the species that nest in the rocky crags of the cliffs are classified as “pelagic birds”. These birds only come to shore to breed, and spend the rest of their life at sea. It is remarkable to me that little of their ocean life is understood, although it is clearly an important part of their life history and hence conservation. One incredible fact from the trip’s crew : common murres may dive up 600 feet in search of food! The images below are just a small cross-section of the birds were observed along the way.
Tufted Puffins are a distinct and charismatic bird. Their large eyebrows stretch over their head in a very peculiar way!
Although a bit slow with the shutter speed, I like the image of this flying tufted puffin because it highlights their beautiful beak and face.
This image of a tufted puffin was taken the day before at the aviary of the Alaska Sea Life Center- A remarkable bird!
This group of parakeet auklets was a treat. They are aptly name – their chatter sounds very much like parakeets!
On the sheer rock faces we were lucky to be shown these thick-billed murres. A lifer for the trip!
In contrast to the thick-billed murres, these common murres do not have a white line behind their bill.
Named for the distinct feather that reached above their eye, a horned puffin takes flight near the Chiswell Islands.
This image of a horned puffin taken the previous day at the Alaska Sealife Center demonstrates its namesake beautifully! The horned extension above the eye is striking!
The bluebird skies of the day blessed us for the nearly the entire trip. However, as we moved away from Northwestern Glacier, a thick bank of fog moved in from the ocean. The damp air made the day cooler, and provided a mystical backdrop to the Chiswell Islands which poked in and out of the fog like chandeliers in a smokey bar. The islands created a partial barrier to the fog which flowed through the lowest points of the islands like a sinewy serpent. Subsequently, the fog established the base of some of my favorite scenery images throughout the day, and featured below.
As we pulled out of Seward harbor the bluebird skies were stunning!
This panoramic shot really captures the setting of the Chiswell Islands. Characteristic of the islands, bright green tops and trees were seperated from the water by a gray band of rock.
Our boat the “Viewfinder” moved past the mainland with the Northwestern Glacier Behind us.
We threw a big wake as the Viewpoint moved to a new location.
As we rounded Granite Island and moved towards to the Northwestern Glacier I captured this panorama across our bow. Brilliant blue skies!
Cataract falls spilled down this large headwater and was fed by a snow/glacial field above.
As we moved back onto the open ocean, heavy fog rolled in from the ocean. Although this island blocked much of the fog, it still spilled through the lowest point of the island like a living creature.
The vertical cliff faces of the Chiswell Islands are often near to each other creating small pasages. I was struck by the lone tree to the upper right of this one, and the fog that lit the scene. I was fortunate to click the shutter as a gull took off far above.
Many of the Chiswell Islands have broad rock arches like the one displayed here.
Several groups of harbor seals float in front of the face of this tidewater glacier near the Northwestern Glacier.
The Northewestern Glacier spill from the Harding Ice Field into the ocean. The “calving” of this glacier, and others in the bay provide the icebergs for the harbor seals.
As whales-of-a-tales go, I’ve stuck to the facts of the day, although so much of was above average that even I feel that it’s a tale of whoppers. It was the type of trip that every subsequent trip to the ocean will be relative to. Perhaps I will tie it someday, but it would take a Moby Dick sized whale of a day to beat it!
Drop a few ice cubes in your drink before you start reading this, and consider the question : how many licks does it take to get to the center of a Tootsie Pop? Now, while you are thinking about that illusive answer, consider how many days it takes to melt a glacier. Just how fast does it happen? My several trips to Castner Glacier over the last 15 months provide interesting evidence into this impossible to answer question. Let’s take a look!
When I first visited Castner Glacier in April 2014 a monstrous, multi-chambered ice cave shook me to my core. The ice cathedral hung over my head an estimated 80 feet above. The walls and ceilings of it were composed of blue, transluscent layers of ice and closer inspection of the walls showed that the clarity of the ice provided a window deep into the glacier of the sediment suspended in it. A chimney was cut into its ceiling allowing light to illuminate the icy floor of the glacier. It was awe inspiring!
This video was taken in April 2014 during a walkthrough of the ice cave and captures the scope of it. Instability of parts of the video was due to the slippery ice floor!
The next time I visited the rainiest summer recorded in Fairbanks was coming to a close, and the rain had reshaped the ice in unimaginable ways. Water ran down the glacier in small rivulets and opened the chimney to a yawning mouth. It degraded the ceiling so extremely, that large chunks of the cavern had crashed down. If you stood close to the mouth of the cave many rocks fell dangerously from the ceiling as they melted from their icy tomb of thousands of years. The rapid melt had removed the beautiful transparency from the ice. It was now silty and gray.
The rapid melting that we witnessed inspired me to create a different type of video for Castner. This video documents the fall (August) stage of plant life around the glacier, and then documents the progression of drops of water from the glacier which eventually build into the silty and fast-flowing Castner Creek.
When I visited the Castner Ice Cave in June 2015, it was just a shadow of its former self. Only a small arch of ice remained of the once huge cave. Castner Creek ran through the remnant of the ice cave, where previously it had run to the side. In just fifteen months, unquantifiable amounts of ice from the glacier had transformed into water, carrying with it many tons of silt to the broader river valley that Castner Creek flowed into. The glacier was rapidly changing, dying.
The answer is two hundred fifty-two. At least that is what students at Purdue concluded to the center of a Tootsie Pop. But why does it matter that Alaska’s Castner Glacier and the state’s other glaciers are melting so rapidly? Alaska Dispatch News recently reported on a new study demonstrating that Alaskan Glaciers are losing 75 billion tons (75 gigatons) of ice each year, and that 94% of that loss is occurring on inland glaciers like Castner. This means that Alaskan glaciers will continue to contribute a significant amount to global sea level rise, especially in light of a warming climate. They end the article with a quote by study co-author O’Neel. “This is probably going to be a pretty tough year for a lot of the glaciers”, he stated. It appears he is right, and Castner’s included.
Our trip had taken us from Fairbanks,Alaska up the Haul Road (Dalton Highway), over Chandlar Shelf, and peaked at Atigun Pass (4,738′). We traversed the valley on the north side of the Brooks Range, and explored as far as Toolik. Although we were on the tundra, we never went far enough to leave the Brooks Range out of sight. Because of the incredible backdrop the mountains provided, I was compelled to place what we observed in their natural habitat. The resulting pictures and galleries provide a slice of diversity of the flowers and birds found on the tundra.
One of the remarkable birds seen during the trip was a bluethroat. These awesome birds are one of a few species which winter in Asia, but breed on the tundra in Alaska. Due to the amount of migration time needed they spend a lot of time on the wing! When we found it with help from another birder, the male bluethroat was displaying in the air and calling out in the voices of many species. Bluethroats are almost perfect mimics, and as it sang out we could hear the calls of redpolls, gray-cheeked thrushes, and swallows in its repertoire. A bluethroat female will find this male attractive if it can mimic enough other birds. The video below captures a few of the calls of this unique and beautiful bird, and shows of its stunning throat!
The northern hawk owl was another great bird of the trip. These raptors are efficient predators and unlike most owls are active during the mornings, evenings, and even during midday. This adaptation arose from the lack of nighttime in the tundra. The hawk owl we found was perched in the dead limbs of a burned black spruce, and actively twisted its head back and forth at every new sound. Suddenly the twisting head stopped, and it fixed its gaze on some unfortunate small animal on the ground. It dove off the branch with tucked wings, swooped low above the shrubs, but then perched again with empty claws. No breakfast this time! The second video below shows the intense stare of this bird.

Yellow, purple, pink, white, and red splashes of color were evident all across the tundra. Each color was associated with a pointed, rounded, tall, or stunted flower and stalk. The flowers of the tundra come in many different colors and shapes! Often the species are associated with a particular habitat type. Alpine arnica were found in the higher alpine tundra, arctic poppies in the short tundra, and bell heather tucked into the low pockets of the tussocks. One of the unexpected flowers of the trip were the frigid shooting stars that lined a small stream south of Toolik Field Station. Although I have wanted to see them for years now, I never thought the first time would be on the tundra! The flowers are aptly named, as their unique shape trails behind them as if they fell from the sky.
I am about to sing the unsong of the mosquito because each bite from the armies of flocked, winged, beasts can cause doubt that they serve any purpose but to cause misery. However, during the trip I documented one of the mosquito’s greatest contributions to the ecosystem. In the tundra, bees and butterflies are not as abundant as they are in forested areas, however, as shown above the variety and abundance of flowers have to be pollinated by something! In step the buzzing, nagging, mosquito. Male mosquitoes do not feed on blood, but rather nectar and thus spread pollen. Their hunger ensures that the blooms of the tundra create seeds and propagate for the next year.
