In November 1952, an Air Force C-124 Globemaster II with 52 passengers and crewmembers aboard crashed near Elmendorf Air Force Base, Alaska. Almost 60 years later, June 9, 2012, an Alaska National Guard UH-60 Black Hawk crew on a training mission noticed some debris on Colony Glacier. The National Guard sent a team on foot to examine the site and they retrieved items that were identified as being from the C-124 crash.Since then, every summer during a small window of opportunity, Alaskan Command and Alaska National Guard personnel have been supporting the joint effort of Operation Colony Glacier.
