CARBONATED SPRINGS. 195

DEADSHOT SPRINGS (COLTTSA 6).
Deadshot Springs are situated along a ravine whosa mouth is about
one-half mile south of the buildings on the Stovall and Wilcox horse
ranch in Bear Valley and about 5 milss southwest of Leesville. The
principal spring issues from a short piece of pipe inserted near the
base of a lime carbonate terrace on the south side of the ravine,
about 1 mile above its mouth. The top of the terrace extends for
about 50 feet along the ravine, and the material exposed in its front,
which is perhaps 20 feet high, indicates that the terrace is composed
largely of serpentine fragments cemented by lime carbonate.
The spring yields about 1^ gallons a minute of carbonated salty
water, 65° in temperature, that is an active cathartic. About 150
yards eastward, below the main spring, a flow of perhaps 6 gallons a
minute of mildly carbonated, salty water issues on the south bank of
the ravine. The water here comes from one main spring and several
seepages from carbonate-crusted patches in a small salt-grass area.
On the north bank of the stream, 300 yards farther down the ravine,
there is a carbonate terrace about 25 feet long and 10 feet wide. A
small pool on its top yields about 1 gallon a minute of carbonated
salty water, 78° in temperature. The material of part of the terrace
is so deeply iron stained that it has an ocherous appearance. The
lowest springs are about 150 yards farther downstream, on the north
edge of the creek, and issue from two crevices about 6 yards apart.
They yield flows of about a quarter of a gallon and 2 gallons a minute
of water that is similar in character to that of the other springs.
All these springs issue from serpentine, which here forms a wide
belt that extends from the valley land westward nearly or quite to
the summit of the mountains and is possibly the northward extension
of the serpentine area at Wilbur Hot Springs. It is worthy of note
that though Deadshot Springs issue from serpentine, and Oil Spring
(Colusa 8, p. 194) a few miles farther south, issues from shale, both
groups of springs yield carbonated salty water and have formed large
carbonate deposits.

QTTIGLEY SODA SPRINGS (LAKE 27).
Three carbonated springs that emerge about a quarter of a mile
from each other on the Quigley place, 14 miles by road north of the
town of Lower Lake, have been surrounded by concrete basins so as
to form drinking pools. One of them is near the western side of Long
Valley Creek and apparently issues from siliceous shales that are over-
lain by basaltic lava which forms a low ridge. The second spring is
farther northwest, on the wooded slope of the lava ridge but close to
the northern edge of the lava. The third spring is still farther to the
northwest and issues at the side of a small ravine from a seam in
