The expedition that traversed the Brooks Range in 1951. From left to right: Bill Brosge, Gordon Herreid, Jack Warne, Dick Olsen, Red Grady, Marvin Mangus, and Bill Patton. The party climbed Brooks Range from north using Weasels (the tracked vehicles in background) and descended southward on the John River by boat. This party was only the fifth government expedition to cross the central Brooks Range. Photo taken on upper John River (Wiseman quadrangle) after completion of the Weasel segment.
