1951 Map of Helena

USGS Topo · Published 1972

About this map

Mining operations and remote homesteads define this mid-century survey of the Trinity Alps region. The Trinity River and its numerous tributaries, including the North Fork Trinity River and Canyon Creek, serve as the primary conduits for settlement and industry. Evidence of the area's gold-seeking history is scattered across the terrain, with prominent sites like the Enterprise Mine, Yellowstone Mine, and Mason & Thayer Mine appearing alongside smaller workings in French Gulch and Rich Gulch.
