148 SPRINGS OF CALIFORNIA.

mum temperature of 100° was recorded in the pools, and the dis-
charge measured was about 450 gallons a minute. The water rises
quietly and has no distinct taste nor odor. Much dark-green algous
growth lines the pools and the discharge channels, and small snails
live in the water.
The springs rise in a flat, salt-grass area about 100 yards south of
the base of lava hills and 15 or 20 yards west of a 6-foot terrace-
like bank that drops eastward toward the river. At' two places
along the edge of this bank springs that have about equal flows of 8
gallons a minute issue with temperatures of 74° and 100°. The
bank was not observed closely enough to be able to determine
whether it is an old bank of Owens River or a small fault scarp.
Like the Casa Diablo Springs, however, the position of the warm
springs in a region of comparatively recent volcanic activity, where
there has also been considerable minor faulting, affords suggestive
evidence of the cause of their thermal character. Other similar
springs rise about 3 miles farther north in the valley and form a
small meadow.

HOT SPRING SOUTH OF BISHOP (INTO 1).
At the base of the Sierra about 8 miles south of Bishop a spring
of considerable flow that is utilized for domestic supply and also for
dipping sheep has a temperature of about 130°.1 Like the springs
farther north, in Long Valley, its water has no distinctive taste nor
odor and is probably mineralized in only small amount.
Volcanic rocks are present a few miles north of Bishop, and lava
cones border the valley several miles south of the spring; but its
water issues from granitic rocks, and the unusually high temperature
seems more probably to be caused by rising from a considerable
depth along a fault zone than by contact with masses of lava that
have not yet cooled.

WARM SPRING NEAR LITTLE LAKE (INTO 32).
A small amount of lukewarm, odorless water issues in a spring
about 300 yards from Little Lake and near the base of a lava bluff
25 or 30 feet high. The spring has not been developed nor used to
any extent during recent years and is known only locally. Perhaps
the chief point of interest concerning it is its position with respect
to the lava bluff. The primary alkaline and saline character of the
water is shown by the following early analysis:
