About this map

Lassen Peak and the surrounding volcanic terrain of the Cascade Range define this high-elevation landscape within Lassen Volcanic National Park. The map documents a complex geothermal environment, centered on the hydrothermal features of Bumpass Hell and Bumpass Hot Springs. Notable peaks like Mt Helen, Loomis Peak, and Eagle Peak overlook a network of alpine basins including Lake Helen and Emerald Lake.

Southward, the terrain transitions into the Lassen National Forest, where high meadows like Brokeoff Meadows and Glassburner Meadows sit among the headwaters of the Mill Creek drainage. The map records specific points of geothermal interest in the southern reaches, such as Morgan Hot Spring and Growler Hot Spring, alongside natural landmarks like Mill Creek Falls and the distinct volcanic form of Brokeoff Mtn.
