The place has become a camping resort for people afflicted with
rheumatism, which is said to be relieved by baths in the hot mud.
Bathing pits are dug in the cooler mud near the spring and the
material is worked up to the desired consistency. Close to the main
spring is an area of steam vents, about 25 by 50 yards across, which
contains several pools that furnish clear water for washing and cook-
ing. This area also furnishes sufficient heat for cooking, kettles
containing food being placed in shallow pits, covered with sacks, and
allowed to remain until the food is done.
Another area of hot vapors and mud in a ravine northwest of the
main spring has been filed on as a placer claim for mining medicinal
mud. The material at this place is somewhat finer in texture than
that at the main spring.
VAPOR VENTS WEST OF COSO HOT SPRINGS (INYO 30).
Along the branches of a ravine 3 miles west of Coso Hot Springs
there is an area several acres in extent in which much vapor issues
and the ground is impregnated with sulphur and alum, but in 1908
no water was flowing. A temperature of 203°, which is probably
the boiling point at this elevation (about 4,300 feet), was recorded in
the vapor vents. These vents are in an area of lava where there are
