Featuring North America’s highest mountain, the 20,320-foot-tall Mt. McKinley, Denali National Park includes more than 6 million acres of diverse ecosystems, mountains and glaciers. Originally established as Mt. McKinley National Park February 26, 1917, the park was incorporated into the larger Denali National Park in 1980. The park was designated an international biosphere reserve in 1976. In this image of part of the park, blue-white glaciers slide down the valleys between the rugged mountains of the Alaska Range. Space Imaging’s IKONOS satellite took this image August 8, 2004.
