Lassen Volcanic Field covers roughly 1066 km² straddling the border of Lassen Volcanic National Park and nearby wilderness areas in northern California. Characterized by recent volcanic activity, the landscape features a dramatic mix of acid fumaroles, silica terraces, radiating lava domes and glacially carved valleys. Visitors come for hiking at high elevations, from the easy walks around Bumpass Hell to strenuous climbs on Lassen Peak itself. The area is also notable for alpine lakes, year-round snowpack and geothermal features that provide insight into plate tectonics and magma movement beneath the surface. Wildlife such as mule deer, black bears and Thamnophis sirtalis inhabit the park, while snowshoeing, camping and cross-country skiing extend the year-round appeal.
