About this map

Hyampom serves as the central hub of this northern California landscape, situated at the confluence of the South Fork Trinity River and Hayfork Creek. The 1951 field survey reveals a mountainous region defined by the vast Trinity National Forest and Six Rivers National Forest. Small settlements and family holdings like Grel Ranch and French Ranch are connected by a sparse network of roads and a prominent Telephone Line that cuts across the timbered ridges.
