Allen Army Airfield — Delta Junction Ft Greely, United States

Allen Army Airfield serves Fort Greely near Delta Junction in Alaska's interior, sitting at 1,291 feet of elevation with three runways supporting military operations. This part of Alaska experiences an extreme continental climate, with long, deep winters and a short summer season, quite unlike the milder coastal climate found in cities such as Anchorage or Juneau. Delta Junction itself marks the northern end of the historic Alaska Highway, a remote community surrounded by vast stretches of wilderness. The airfield mainly supports the needs of the military installation at Fort Greely rather than public passenger traffic, and access here stays generally restricted rather than open to commercial bookings. Interior Alaska's isolation makes reliable air access essential for both military and civilian purposes across this thinly populated region.
