104 SPRINGS OF CALIFORNIA.
HOT SPRINGS ON MANZANITA MINING PROPERTY (COLTTSA 10).
Between Jones and Wilbur hot springs, on a strip of land that is
part of the Manzanita mining property, similar hot sulphur springs
issue in at least three places. The spring farthest east, which has been
mentioned in connection with Wilbur spring No. 1, forms a pool a few
feel in diameter that yields perhaps 1 gallon a minute of sulphureted,
salty water, 110° in temperature. It is clear and distinctly yellow in
color, like that of the Main Springs at Wilbur's, and like the latter
shows a deposit of sulphur on its surface. In 1910 the spring was
protected by a roof and was occasionally used as a foot bath. An-
other spring farther upstream, on the northwest edge of the creek,
was protected by a tent and used for bathing; the third spring is
about 100 yards northeast of Jones's Fountain of Life spring. The
third spring, which is between the creek and the wagon road, issued
from a wooden curbing near an old, unused bathhouse and yielded
perhaps 1| gallons a minute of sulphureted salty water, 142° in tem-
perature. All three of these springs issue in an area of serpentine,
but the saline content of their water is probably derived from the
altered sediments that outcrop a short distance to the west along the
upper course of Sulphur Creek.
BLANCKS HOT SPRINGS (COLUSA 12).
A number of years ago there was a small hot-spring resort, known
as Blancks Hot Springs, about half a mile west of Jones Hot Springs
(Colusa 11, p. 103). When the Wideawake mining shaft was sunk
near by, Blancks Hot Springs ceased flowing and the resort was
closed, but of late years, since the shaft has been abandoned and has
become partly filled up, the springs have resumed their flow. In
1910 there were two springs in a small ravine behind a former room-
ing house. One of them yielded perhaps 2 gallons a minute from a
vertical pipe that extended a foot above the surface, and the other,
a few yards away, discharged about an equal amount through a pipe
that extended to a tub in a small bathhouse near by. The water is
sulphureted and salty, and, like that of several other springs in the
locality, it is clear yellow in color. It issues from sandstone that is
well exposed and dips almost vertically to the northwest.
HOT SPRINGS AT ELGIN MINE (COLUSA 7).
The Elgin quicksilver mine is situated on the western side of
Sulphur Creek, on steep slopes 400 to 500 feet above the stream.
Much work has been done in these mines and occasional rich pockets
of cinnabar have been found, but the tunnels have been very diffi-
cult to work in because of the high temperature, the hot water, the
sulphureted and ammoniacal vapors, which affect the eyes as well as
the respiration, and the acid salts, which quickly destroy clothing.
In addition to the cinnabar considerable amounts of sulphur were
