CARBONATED SPRINGS. 193

CAEBONATED SPBINGS AT SOUTHWEST EDGE OF CLEAR LAKE (LAKE 37).
About 5 miles southeastward around the west side of the lake from
Soda Bay small warm carbonated springs issue for a distance of 25
yards along the lake margin. A quarter of a mile farther south
numerous other springs rise within a stretch 200 yards long. One of
the largest noted had a temperature of 100° and a flow of perhaps
1 gallon a minute. Its water was moderately carbonated and also had
a noticeably " sharp " taste that was possibly due to free carbonic acid.
At both of the localities mentioned there is considerable iron-stained
cemented gravel and sand.
The rock that is exposed from about 2 miles west of Soda Bay,
eastward and southward around the lake to and beyond the springs
just described, is the andesite of Mount Konocti. There appears to
be a close relation between the numerous warm carbonated springs
and this comparatively recent lava. The thermal character of the
springs at Soda Bay and farther southeast has been noted in the
description of the springs at Sulphur Bank (p. 99). Their carbonated
character is also noteworthy in connection with the presence of the
lava. This association of lava with carbonated springs at several
places has already been mentioned, and it is brought out in the tabu-
lated arrangement of the carbonated springs (pp. 250-253).
BAKER SODA SPRING (LAKE 53).

A small carbonated spring, known as Baker Soda Spring, lies
about halfway between Lower Lake and Reiff post office. Its water
has been used to small extent for drinking, but in 1910 it had not
been commercially developed and was of only local interest. Like
most of the other carbonated springs in Lake County, it issues from
sedimentary rocks, probably of pre-Cretaceous age.

GRIZZLY SPBINGS (LAKE 29).
Grizzly Springs (PL XIII, B, p. 242), which have also been known
as Richardson Springs, issue on the northern side of Grizzly Canyon,
about 2J miles above its junction with Cache Creek. As the springs
are beside a main road that leads up the canyon and across the
divide into Colusa County, they have been known for many years, but
they have been improved only since about 1908.
There are two springs on the property. The Main Spring has
formed a prominent carbonate deposit that extends down to the
creek and is crossed by the road. The water rises with continual
bubbling in a cemented rock-walled pool beneath a shed roof and
yields about 2 gallons a minute of moderately carbonated and notice-
