1951 Map of Helena

USGS Topo · Published 1966

About this map

The North Fork Trinity River and its rugged tributaries define this mid-century look at the gold-mining history of the Trinity National Forest. The map documents a landscape transitioning from active extraction to memory, marking formerly significant settlements as Canyon City (Site) and Coleridge (Site). The concentration of hard-rock mining is evident along the eastern gulches, where claims like the Alaska Mine, Enterprise Mine, and Mason & Thayer Mine are recorded alongside the Dedrick Lookout.
