The Blue Ice Caves
Every color has a pure form that boggles the mind and goes beyond the eyes ability to see and it and the brain’s ability to interpret it. I’m talking about hues of color that make your neurons tingle as they try to absorb its hues. You may think of the dark red of a fine ruby or the electric-green of a buggy-eyed tree frog in a rain forest. These pure colors attract us like flies to honey and are a primary reason that thousands of visitors take the risk of stepping into the Mendenhall Glacier to see its sculpted walls of cerulean blue ice. The ice of the cave walls and ceiling is shaped into waves by the wind and water. Immense pressure from hundreds of feet of ice above compress the ice into perfect clarity giving a view to the conditions within.Glaciers carry the earth in their walls and as they melt create new land. As I stepped into Mendenhall Glacier, the world trapped within was immediately evident. Far into the ice, large boulders and sheets of sediment could be seen within. The rocks were distorted by the curves of the ice face. At the base of the cave’s walls, ice flowed over rocks that were half in and half out of their century-old entrapment. The whole floor of the glacier was made from the boulders that melted from glacier. These boulders, it seems, are released at a rapid rate, as the glacier was much different than my last visit in 2015.
Change at Mendenhall Glacier
Mendenhall Glacier is receding up to 150 feet per year. The rapid rate of change was in full display. I was astounded to see former site of the ice caves that I visited in 2015 was ice free. In its place, was a valley of rocks and a frozen river. Rock walls extended up to the ice face high above us. Although I cannot be sure how far the ice receded, it may have receded as much as 300 feet. This is not the first time I have seen such change in an Alaskan glacier – I was reminded of the demise of the ices caves of Castner Glacier over the course of a couple years. Glacial change can happen at a rapid pace! The images below capture the glacier as it is now – I look forward to documenting its inevitable change in the future.
