Hot Creek Geological Site
Overview
Hot Creek is one of the most dynamic geothermal sites in the area and a vivid reminder that Mammoth Lakes sits atop an active volcanic system. Roughly 760,000 years ago, the massive eruption that created the Long Valley Caldera left behind a partly molten magma chamber that continues to heat groundwater deep below the surface. That superheated water rises through fractures and meets the cold flow of the Owens River, creating steaming pools, fumaroles, and travertine terraces visible today. Temperature and vent activity can shift overnight: a clear sign of the living volcanic system beneath the region.
Note: Swimming and wading are prohibited due to extreme geothermal temperatures.
