1956 Map of Mt. Harkness

About this map

Lassen Volcanic National Park dominates the northern reaches of this mid-century landscape, a terrain defined by its geothermal activity and volcanic history. The map highlights hydrothermal features like Terminal Geyser, the bubbling Boiling Springs Lake, and the steam vents of Devils Kitchen. These natural curiosities are accessed via the rustic resort at Drakesbad, established long before the park's formal creation. Further south, the high meadows and forests of the Lassen National Forest are carved by the North Fork Feather River and Gurnsey Creek.
