Great Gorge of the Ruth Glacier, Alaska Range, Denali National Park, USA.
Granite cliffs soar a mile above the mile-wide Great Gorge of the Ruth Glacier 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.Add to Cart Add to Lightbox Download
