Impressions Of Nature: Majestic Wilderness: Margerie Glacier and Mount Root

Margerie Glacier is a relatively stable tidewater glacier in Glacier Bay, Alaska, within the boundaries of Glacier Bay National Park and Preserve.  Margerie is about 21 miles long, 1 mile wide, with an ice face that is about 250 feet high above the waterline.  The glacier begins on the southern slopes of Fairweather Mountain's, Mount Root, an elevation of 12,860 feet (3,920 m), on the Alaska–Canada border flowing southeast down the valley, then turning to the northeast toward its terminus in Tarr Inlet. Margerie Glacier is one of the most active and frequently visited glaciers in Glacier Bay. The glacial ice appears blue as a result of the absorption of red, orange, yellow and green wavelengths of light and, consequently, pools of melt-water on top of the glacier will appear bright blue.
