Few places on earth are as serene, remote and stunningly beautiful as the ice-filled granite valleys of the Alaska Range that surround Denali, the tallest peak in North America. For the mountaineering staff of Denali National Park and Preserve, the time has come to once again set up base camp for the annual climbing season. 

This year, as they have done in the past, the U.S. Army took advantage of the opportunity to assist the National Park Service in moving supplies from Talkeetna to the section of the glacier that will serve as base camp, which sits at 7,200 feet on the Southeast Fork of the Kahiltna Glacier – the world’s longest with a span of 43 miles.

For the Soldiers and Mountaineering Rangers, it’s a win-win situation that provides an opportunity to train in difficult, high-altitude and often inhospitable terrain while efficiently moving thousands of pounds of gear and supplies from one place to another in a matter of hours. 

The operation involved the use of three CH-47F Chinook helicopters and aviators from the 1st Battalion of the 52nd Aviation Regiment stationed at Fort Wainwright.
