Mammoth Hot Creek

The area of Mammoth Mountain is "geologically active" with the areas east and northeast of Mammoth Mountain having numerous hot springs.  An early morning drive into the remote backlands north of the Mammoth Airport will reveal numerous pillars of steam rising from remote areas of the Long Valley floor.  Many of these hot springs are unimproved, simply left to the amusement of grazing cattle.  A couple have been commercially improved; with about a half dozen others on Inyo National Forest land having been noncommercially improved by volunteers.
