Bettles Lodge, a few miles from Bettles, Alaska on the south bank of the Koyukuk River, in the Brooks Range, was built in 1951 by Warren Killen and Wilfred Evans. It has served as a hotel and restaurant, and has been known as AHRS Site No. BET-100. It was listed on the National Register of Historic Places in 1997; the listing included two contributing buildings: a first lodge built in 1948 and a second built in 1951. The lodge buildings are significant as the oldest (first) in the community that grew there, that serves as an air transportation hub for the northern interior area of Alaska.
