Rex Mine, Bob Mine, and the Elkhorn Queen Mine crown the northern highlands of this Jefferson County landscape, highlighting the area's deep-rooted connection to mineral extraction. Situated south of these workings, Tacoma Park and the settlement of Blazing Place overlook a complex network of drainage gulches including Tacoma Gulch and Watertank Gulch. The southern portion of the map is defined by the wider valley of the Boulder River, where the Carey-Twohy Ditch and Lazy T Ranch represent the region's agricultural and water management history. This 2011 survey documents a rugged Montana terrain where high-elevation mining claims transition into irrigated river bottoms, connected by forest roads like NFD 517 RD and primitive trails such as Rodeo Trl.
