300 SPRINGS OF CALIFORNIA.

FELTS SPRINGS (HUMBOLDT 5).
Felts Springs are situated 5J miles by road and trail northeast of
Fortuna. The property was formerly used as a resort, but one hotel
burned in 1878 and another in 1894, and since that time the place
has been abandoned.
The group includes three springs that lie close together near the
top of a hill from which the timber has been cut. The largest spring
rises in a reservoir or well 24 feet deep and 6 feet in diameter and
yields about half a gallon a minute of saline water. One of the other
springs is also saline, and the third is mildly sulphurated. A small
amount of gas rises in each spring.
Soft sandstone that contains fossil shells is exposed near the
springs and to the south and west there are sand dunes. The saline
and sulphureted constituents of the waters are evidently derived from
the marine sediments from which the springs issue.

SALT SPRINGS ON NORTH FORE OF AMERICAN RIVER (PLACER 9).
On the western bank of North Fork of American River, about 2
miles east of Colfax, there are a few saline and alkaline seepages that
are known to local hunters as salt licks or deer licks. Springs that
yield perhaps 10 gallons a minute issue 25 or 30 feet above the river
from the canyon side. There is said to be a considerable saline deposit
along their courses in summer, but when the locality was visited the
small deposit that was seen consisted mainly of soda and alum. Th,e
surrounding rock is slate of Carboniferous age, which has been described
by Lindgren.1 The saline material is apparently derived from these
old sediments.
VALLEY SPRINGS (CALAVERAS 1).
Two small saline springs issue about one-half mile east of Valley
Springs station on the branch railroad from Lodi. eastward into the
mountains bordering Sacramento Valley. One spring is a mere
seepage, but the other yields about 1 gallon a minute of water having
a temperature of 75°. In the summer of 1909 this water was being
bottled for use as a mineral table water. The following partial
analysis shows that the water is primary and secondary saline in
character.
