Matanuska Glacier is a valley glacier 27 miles long by four wide. It is one of the longest glaciers accessible by car in the United States. It's terminus is the source of the Matanuska River. Located near the Glenn Highway about 100 miles northeast of Anchorage, Alaska. The glacier is "active" and expands around one foot per day.
For several days in late June 2010 I photographed this beautiful moving glacier. With crampons on my feet I scrambled further and deeper up the glacier exploring the shapes of naturally sculptured ice, colors, and textures.
Some people ask me why is the ice so blue? When snow falls on a glacier, through time it is compressed, and becomes part of the glacier that winds its way downward by gravity. Air bubbles that are trapped in the ice are squeezed out and the size of the ice crystals increase, making it clear. Glacial ice appears blue because compacted ice absorbs most wavelengths of light and reflects blue light. The deepest blue ice is found in crevasses, towers, and chunks of ice that have calved. And on cloudy days like these the color appears the richest.
