About this map

Hyampom and Hayfork stand as the primary centers of human activity in this Northern California wilderness surveyed shortly after the turn of the century. The drainage of the Trinity River and its major tributary, Hayfork Creek, dictates the movement across the landscape, with high-elevation landmarks such as Thompson Peak and Ironsides Mtn providing navigational anchors. This advance sheet, produced under the direction of George Otis Smith, focuses on the extreme relief of the region, where narrow canyons and steep ridgelines separate small mountain communities. The mapping of Keystone Meadows and various named drainages like Don Juan Creek suggests a period when local knowledge of water sources and summer grazing lands was essential for survival and commerce in Trinity County.
