About this map

Lassen Volcanic National Park dominates this 1985 survey, revealing a landscape defined by its geothermal activity and high-altitude terrain. The map documents numerous thermal features concentrated in the central-east, including the famed Sulphur Works, Bumpass Hell Mud Pots, and several steam-emitting Fumaroles. These landmarks are situated along West Sulphur Creek and Sulphur Creek, illustrating the intersection of active geology with the park's hydrological system.

Outdoor recreation and infrastructure are well-established here, with the Entrance Station providing access to high-elevation lakes such as Lake Helen and Emerald Lake. Beyond the park core, the map extends into Lassen National Forest, showing quiet locations like Brokeoff Meadows and Glassburner Meadows. Significant elevations like Lassen Peak, Brokeoff Mountain, and Mt Diller provide a topographical framework for the numerous drainage systems, including Digger Creek and the North Fork Bailey Creek.
