Springs
Flowing at 84°F virtually roadside at 4,500 feet elevation near the California-Nevada border, these thermal springs emerge 31 degrees warmer than ambient air in terrain associated with Lassen County. Located just 14 meters from pavement, the springs occupy a transition zone where Sierra Nevada and southern Cascade Range geologic influences converge in northeastern California's Warner Mountains region.
The springs emerge from forested uplands receiving 11 inches of precipitation and 31 inches of winter snowfall, supporting juniper woodlands and sagebrush steppe vegetation. Elevations around 4,500 feet mark the zone where Great Basin flora meets montane species, creating diverse habitat in a landscape shaped by Cenozoic volcanic activity and Basin and Range faulting. The Madeline Plains extend eastward into Nevada from this border zone.
Despite Wikipedia references to Scovern Hot Springs, Agua Caliente, and other southern Sierra Nevada thermal features, no clear connection exists to these particular springs in the Warner Mountains of Lassen County. The generic "Springs" designation suggests either undocumented status or confusion in the historical record. The area saw limited Euro-American settlement until late 19th-century ranching and timber operations established small communities like Janesville nearby.
Accessible year-round from paved roads, though winter snowfall may temporarily close higher routes. The immediate roadside location requires no hiking. At 84°F, water temperature is tepid for soaking; visit during cooler months for best experience. Janesville provides minimal services; Susanville lies 40 miles south with full amenities. Verify exact location as generic "Springs" names are common in Lassen County's thermal-rich landscape.
