1979 Map of Trinity Mtn

USGS Topo · Published 1980

About this map

Trinity Mtn and North Trinity Mtn anchor this high-elevation landscape along the border of Humboldt and Trinity Counties. The terrain is characterized by a dense network of ridges and watercourses within the Six Rivers National Forest, including the prominent Devils Backbone and the winding Horse Linto Creek. This late-1970s survey captures a wilderness interface where the Salmon-Trinity Alps Primitive Area meets managed forest lands, marked by an indefinite boundary.
