Unnamed Thermal Spring
Within Modoc National Wildlife Refuge near Alturas, this 72-degree thermal spring occupies protected habitat at 4,360 feet elevation, with restricted public access designed to preserve waterfowl and wetland resources.
The spring flows within refuge boundaries managed primarily for waterfowl conservation, surrounded by wetland vegetation and meadows. The high elevation setting experiences long winters with over 43 inches of annual snowfall, creating a landscape where the thermal water provides unusual warmth in an otherwise frozen environment.
Access to this spring is restricted to protect wildlife habitat and waterfowl breeding areas. Contact Modoc National Wildlife Refuge for information about any available viewing opportunities. The remote location near Alturas and heavy winter snowfall limit access to summer months only.
Geologically, the spring indicates modest geothermal circulation at 21 degrees above ambient in the Modoc Plateau region. The U.S. Fish and Wildlife Service manages the refuge to protect vital wetland habitat and migratory bird populations, restricting access to preserve these ecological functions.
