SACAD: John Heinrichs Scholarly and Creative Activity Days


Glaciers cover much of the 49th U.S. state of Alaska. While many of these are deep blues, just as many are “rock” glaciers which means the glacier is covered in sediment. This sediment can be transported many miles through the mountain ranges. With the current climate melting these glaciers they are receding. Sediment and rock samples can now be safely collected from different locations where glaciers have released sediment that was locked in the ice for an untold number of years. Much of the USGS data comes from the 1940’s through 1960’s due to the size and remoteness of Alaska. Much of the Alaska Range remains capped in ice but the sediment being dropped by these glaciers give a new look into the rocks trapped beneath the ice. These rocks can be analyzed against the geological maps to see how far Castner Glacier transported sediment and analyzed to see if the geological map was correctly labeled in a remote part of the state.
