54 SPRINGS OP CALIFORNIA.

Jordan Hot Springs rise through lime-cemented, granitic gravel,
and the surrounding slopes are of granitic rocks. Three or 4 miles
northward, however, there is some lava, and although it was not noted
in the immediate vicinity of the Jordan springs, its presence near the
lime carbonate deposits at Natural Bridge and in Kern River canyon
suggests that the presence of carbonates or bicarbonates and free
carbon dioxide in the water of Jordan Hot Springs is in some way
related to lava rocks.
BLANEY MEADOWS HOT SPRINGS. (FEESNO 5).
About 75 miles northward from the Jordan springs, in the canyon
of South Fork of San Joaquin River, about a mile above the upper
end of Blaney Meadows, three or four small springs issue on each side
of the river and, like the Jordan springs, are used as a mountain
camping resort. They have been dug out to form bathing pools.
The water has a maximum temperature of about 110°, and the yield
on each side of the river is perhaps 20 gallons a minute. The follow-
ing is an analysis of water from the largest spring on the east side
of the river:

The water of the springs is characterized chiefly by primary salinity
with secondary salinity as a subdominant property. The concen-
tration is sufficient to render the water undesirable for many indus-
trial uses, and its salinity is sufficient to be noticeable in taste.
