1939 Map of Halls Flat

About this map

Modoc National Forest and Lassen National Forest converge on this 1930s landscape, where volcanic topography meets early California ranching and timber interests. The presence of Subway Cave, Ice Cave, and the Devils Half Acre highlights the unique geologic character of the region, anchored by peaks like West Prospect Peak and Raker Peak. The map documents a working landscape dotted with family operations such as the Ward Ranch, Dixie Ranch, and Russell Dairy. Industrial and government infrastructure is well-established, evidenced by the Western Pacific and Pacific railroads cutting through the valleys, alongside several outposts like the Halls Flat Ranger Station. The Emigrant Trail remains a visible historical thread across the southern portion of the quadrangle, linking the era of settlement to the early 20th-century forest management era.
