1951 Map of Hyampom

About this map

The South Fork Trinity River carves through the heart of this mountain landscape, meeting the Trinity River near Big Bar. In the early 1950s, the isolated valley community of Hyampom serves as a central hub, complete with a Landing Field and the Hyampom Guard Sta. The terrain is characterized by high ridges like Halfway Ridge and Pelletreau Ridge, separated by deep gulches and creek drainages. Significant human activity is evidenced by remote outposts and family-named holdings, including Grel Ranch, French Ranch, and specialized locations such as Camp Trinity and Camp Carter. Geologic and recreational interests are marked by the Butter Creek Caves and Big Slide Camp Ground, while the high-elevation Haypress Meadow suggests a history of seasonal grazing within the Six Rivers National Forest.
