1956 Map of Lassen Peak

About this map

Lassen Peak dominates the northeastern corner of this mid-century survey, surrounded by the geothermal activity and dramatic volcanic geology of Lassen Volcanic National Park. The map documents early recreation and infrastructure within the park, from the hydrothermal features at Bumpass Hell and the geothermal activity of the Sulphur Works to several designated camping areas like Black Oak Campground and Mineral Campground. South of the park boundary, the landscape shifts toward industrial and rural life, marked by the presence of Forward Mill and the Rockland School.
