334 SPRINGS OF CALIFORNIA.

eastern sections, many springs of very small flow have become impor-
tant because of their positions, for they may furnish the only water
within a radius of 10 or 15 miles. Some of these desert springs yield
water of poor quality, as it contains noticeable amounts of alkaline
salts, but as they afford in some places the only available supplies
they are welcome watering places.
The following descriptions cover most of the perennial springs
which were visited or concerning which reliable information was
obtained, together with a few minor fresh-water springs that are in
the same localities as mineralized springs which have been described.
The springs are taken up in order from north to south along the
eastern part of the State through the northern lava region, the Sierra,
and the eastern and southeastern desert ranges, and then from south
to north through the Coast Ranges. This order of discussion gives
a convenient arrangement of the springs with regard to topographic
and climatic conditions.
Other springs of similar character but mainly of lesser importance
are briefly described later under the heading "Springs that are less
well known," but the locations of these springs are not shown on
Plate I (in pocket).
POTHOLE SPUING (MODOC 1).
A few springs of relatively small flow afford watering places for
range cattle in the lava-covered region of western Modoc County.
One of these, Pothole Spring, is situated in a small marshy area at
the western base of Blue Mountain, about 35 miles northwest of
Alturas. The water rises in a deep clear pool a few fset in diameter
and is noticeably above the normal temperature but probably less
than 70°. The flow is small and the water sinks in the marshland a
short distance from its source.
BOTTLE SPRING (MODOC 2).
Bottle Spring is about 10 miles south of Pothole Spring and near
the northern end of Fairchild Meadow. It yields cold water and the
amount is said to vary greatly with the season.

COOL SPRINGS AT CAMPBELL HOT SPRINGS (SIERRA 2).
Two cool springs that furnish domestic supplies are situated on the
grounds of Campbell Hot Springs, near Sierraville. These have been
mentioned in the descriptions of the principal springs at the resort,
and an analysis of water from the main cool spring has been given.
(See p. 129.) Both cool springs are of slight flow, but they are con-
veniently situated and yield good water for cooking and other
household purposes.
