1922 Map of China Flat

About this map

The South Fork Trinity River carves a deep path through this 1922 tactical survey, defining the rugged geography of the Trinity National Forest. This era of the California wilderness is marked by isolated outposts and early administrative sites like the China Flat Post Office and Handy Horse Ranger Station. Settlement is sparse, clustered primarily around small holdings such as Quinby, Uptons, and Irvings along the river's eastern banks.
