Mountains of the Alaska Range dwarf a CH-47F Chinook helicopter from D Company, 1st Battalion, 52nd Aviation Regiment as it carries equipment and supplies from Talkeetna to the Kahiltna Glacier base camp on Mount McKinley April 27, 2015. Soldiers and Chinooks from the D/1-52d "Sugar Bears" made short work of delivering several thousand pounds of equipment to base camps at 7,000 and 14,000 feet for the 2015 climbing season, saving money and time for the National Park Service and gaining invaluable experience operating at altitudes and in terrain not available for training missions outside Alaska.
