Description
Layer upon layer of time is shown on this small iceberg in Disenchantment Bay, Alaska. White layers are caused when snow fell when it was very cold, trapping air within the ice crystals. The clear blue ice comes from the opposite extreme, where no air was trapped in the snow due to warmer or even wet conditions. Soil may also be deposited on the surface of the snow. This snow with or without air and soil is compressed by the weight of new snow above and becomes ice which falls into the sea at the terminus of the glacier.
Hubbard Glacier is located in eastern Alaska, United States, and part of the Yukon Territory, Canada. It's terminus is located in Alaska where Wrangell St. Elias National Park meets Disenchantment Bay. It is estimated that the icebergs in Disenchantment Bay are 450 years old.
