About this map

Boulder River flows through the northwestern corner of this territory, where an intricate system of irrigation canals including Clause Ditch, Smoot Ditch, and Ellison Ditch divert water toward the agricultural plateau of McKenzie Flats. The landscape transitions sharply into the high country of the Gallatin National Forest, a region defined by steep canyons and prominent peaks like Black Butte and Red Mountain.

Evidence of resource extraction is found deep within the timbered draws at the Calcite Mine (Inactive) near Calcite Gulch. Access to this remote terrain during the mid-1950s relied on a network of rugged paths, including a Pack Trail and a Jeep Trail winding through Rudd Canyon. The map records specific points of entry and crossing such as the Eightmile Bridge, which serves as a vital link between the river bottom and the ascending gulches of Ross Canyon.
