About this map

The South Fork Trinity River snakes through the high-elevation divide where the Six Rivers National Forest and Trinity National Forest meet. This 2018 survey reveals a landscape of massive ridges and deep drainages, including the towering South Fork Mtn and Potato Hill. Notable clearings and openings, likely significant to local forest management and history, include Waterbarrel Opening and Smith Opening.

Access across this challenging terrain is marked by remote infrastructure such as the Mule Bridge over the river and the Mule Spring landmark. The boundary between Humboldt Co and Trinity Co cuts through the eastern half of the map, separating the river valley from landmarks like Castle Rock and Bennett Peak. Forest routes such as Manzanita Ranch Rd and Lake Mountain Rd provide the primary transit through the dense drainages of Grouse Cr and Grapevine Cr.
