Spc. Mark Aderholt, B Company, 1st Battalion, 52nd Aviation Regiment, keeps an eye on the gauges as part of the startup for a CH-47F Chinook helicopter. Aderholt was part of three crews from the U.S. Army Alaska Aviation Task Force that spent the week in Talkeetna, Alaska, training in high altitude flying through the Alaska Range. The mission for Sunday, April 24, included continuing a longstanding partnership with the National Park Service to shuttle equipment and supplies to the Park Service base camp on Kahiltna Glacier for the upcoming climbing season on Denali.
