The Grant-Kohrs Ranch National Historical Site and the extensive Deer Lodge Prison Farm anchor the northern reaches of this Montana landscape. In the mid-1990s, the region demonstrates a dense overlay of institutional and industrial activity, from the Warm Springs State Hospital complex in the west to the numerous mining claims dotting the Helena National Forest. The map traces the corridor of the Burlington Northern railroad as it connects major centers like Butte and Deer Lodge, passing through smaller settlements such as Opportunity, Galen, and Rocker. High-elevation mining remains a defining characteristic of the terrain, with names like the Saratoga Mine, Free Enterprise Mine, and Morning Glory Mine appearing across the slopes of Bison Mountain and Sugarloaf Mountain. This detailed survey also captures specialized land uses, including the Warm Springs State Wildlife Management Area and Boulder Hot Springs.
