The Bureau of Land Management’s Billings Field Office (BiFO) tasked GeomorphIS and its team partners, Hope Archaeology Inc. and U.S. West Research, Inc., to conduct a Class III inventory of the Hoskins Basin Archaeological District in Yellowstone County, Montana. The Hoskins Basin Archaeological District was created to recognize a conical timber lodge and cribbed log structures, along with a habitation site. The cribbed log structures and conical timber lodge were rare for this location within Montana when the District was established in 1973. Since establishment of the District, a number of additional cultural resources have been documented within the 2,610 acre District.
