132 ' SPRINGS OF CALIFORNIA.

FALES HOT SPBINGS (MONO 1).
Fales Hot Springs are about 13 miles northwest of Bridgeport, on
the main road to Minden, Nev. In 1908 there was a stage station
and road house at the place, and plunge and tub baths were provided
for use of the water. The place was too inaccessible to have become
much of a resort, but during the summer months it was visited by
campers.
The hot water rises along the bed of a small creek that has been
dammed to form a bathing pool and to keep the water at a com-
fortable temperature, for in the main group the temperature ranges
from 129° to 141°. Measurements indicated that the total discharge
was about 300 gallons a minute. Much gas, probably carbon dioxide,
rises with the water, which is too hard for use in laundry work.
Hard, shiny nodules occasionally found in the creek are probably
composed mainly of lime carbonate, though they may contain con-
siderable silica. No other deposit of note is formed at the springs,
but on the hillside 400 yards north of east from and 125 feet higher
than the present springs there is a circular lime-carbonate basin, about
100 feet in diameter and 25 feet deep, with a rim 50 to 150 feet thick.
Another smaller lime carbonate deposit lies halfway between this
basin and the springs, and a third deposit of the same material ap-
pears along the creek side 250 to 400 yards east of the springs. Hot
water no doubt formerly issued at these places and built up the
deposits.
The region east of the springs and apparently the higher slopes
that surround them are granitic, but the slopes near by are of lava.
Less than 50 yards northwest of the springs is a knoll of lava that is
considered by E. S. Larsen, jr., to be quartz latite. Along the creek
banks on each side of this material the rock has been so completely
decomposed to a clay as to suggest that the lava is an intrusive mass
or dike. If this is true, it is probable that the heat of the water and
also its chemical contents are derived from the lava. The association
of lava with lime carbonate deposits at hot springs has been mentioned
in the descriptions of a few other springs, and seems worth calling
attention to again in connection with the springs at Fales.
BUCKEYE HOT SPUING (MONO 2).
Buckeye Hot Spring is about 5J miles south of west from Bridge-
port and on the north bank of Buckeye Creek, a mile above the mouth
of its canyon and 40 feet above the stream. The water issues with a
temperature of 140°, and perhaps 25 gallons a minute flows down to
the creek over a large domelike overhanging deposit of lime carbonate.
In 1908 a part of the water was conducted across the creek in a small
trough to a cabin in which there were two wooden bathtubs; but
