About this map

The Trinity River and its major tributaries carve through the heart of the Trinity National Forest in this early twentieth-century survey of Northern California. Mining and frontier outposts such as Dedrick, Coleridge, and Canyon City are concentrated in the steep drainages of the northeast, where Canyon Creek and the North Fork Trinity River create complex topography. The map documents a rugged landscape defined by high peaks like Ironside Mtn and Twin Sisters Mtn, alongside specialized camps like Stove Camp and Blue Ridge Post Camp.

Southward, the settlement patterns follow the river valleys, with Junction City and Hayfork serving as key nodes in the mountainous interior. This period of the forest's history is captured before modern development, showing the connectivity between isolated spots like Hyampom and Burnt Ranch. Local landmarks, including Keystone Meadow and Eightmile Ridge, provide a detailed look at the land use and navigation routes used by early twentieth-century surveyors R.B. Marshall and J.P. Harrison.
