Ruth Amphitheatre, Great Gorge, Alaska Range, Denali National Park, USA.
Ice collected in the Ruth Amphitheatre funnels through the mile wide Great Gorge of the Ruth Glacier between mile high granite cliffs in Denali National Park and Preserve, Alaska, USA. Flightsee over a vast wilderness of glaciers and icy peaks in the Alaska Range. Ruth Glacier was 3800 feet thick in 1983 and flows 3 feet a day from Denali (20,310 feet or 6191 meters, aka Mount McKinley), the highest mountain peak in North America. Denali is a granitic pluton uplifted by tectonic pressure while erosion has simultaneously stripped away the softer sedimentary rock above and around it. Photo by Carol Dempsey.
