1985 Map of Chessman Reservoir

About this map

Rimini and the surrounding high country of the Northern Rockies are documented here during the mid-1980s, revealing a landscape defined by its mining heritage and public land boundaries. The map illustrates the convergence of the Helena National Forest and Deerlodge National Forest, with numerous labels for Prospect and Mine Shaft locations indicating decades of extraction across the Frohner Basin and Catarat Basin. Water management for the region is anchored by the Chessman Reservoir, while the presence of the Buffalo Trail and the remote settlement of Nellie Grant highlight the historical transit routes and small outposts that once supported the local mining economy. The terrain varies from the high Occidental Plateau to deeply carved drainages like Lump Gulch and Tenmile Creek.
