1979 Map of Sims Mountain

USGS Topo · Published 1979

About this map

The South Fork Trinity River carves a deep path through the eastern portion of this terrain, marking the division between Humboldt and Trinity counties. This 1970s landscape within the Six Rivers National Forest is defined by steep relief, rising from the river to peaks like Sims Mountain and Bennett Peak. The map reveals a network of high-elevation trails and remote outposts, including the South Fork Mountain Trail and the South Fork Trail, which follow the primary ridges. Human presence is concentrated around isolated sites such as Margarita Ranch, Lake Mountain Ranch, and the Dan East Cabin. Notable landmarks for local history include Mule Bridge crossing the river and several springs and openings, such as Waferbarrel Opening and Black Fox Spring, which indicate the critical importance of water sources in this high-country environment.
