218 SPRINGS OP CALIFORNIA.
Ager and Klamath Hot Springs (Siskiyou 7, p. 120). This deposit is
about 75 yards in diameter and is built up prominently above the
flat that borders the creek. Upon it there are six springs that yield
small flows of carbonated saline water. The largest spring forms an
oval pool 3 by 6 feet across and 2 feet deep, in which a temperature
of 72° was recorded. Its discharge is about 2 gallons a minute.
Another pool 10 inches in diameter also yields about the same amount
of water, whose temperature is 76°. The other basins are small, of
less discharge, and of lower'temperatures. There are three other low
mounds in this area of lime carbonate. One of these is entirely
extinct; the other two have only seepage flows from basins 3 or 4
inches in diameter. .
On the hillside about 300 yards northeast of the main carbonate
deposit there is a prominent mound which is nearly 100 feet in
diameter and 10 feet high on its upper side. A shallow pool 5 feet
in diameter that is situated on its top yields perhaps 2 gallons a
minute of carbonated saline water 74° in temperature. At the
roadside, 50 yards below it, there is another low iron-stained mound
from whose top there is a seepage flow of warm water similar to that
of the other springs. White deposits on the hillside a short distance
northward indicate that carbonated water formerly issued there
also.
Material from the deposit that was first described has been used
on an adjacent portion of the wagon road, for the carbonate is easily
loosened by pick and forms a road material that soon packs to a
firm surface.
The water has been used by range stock as a substitute for a salt
lick, but it is too warm and too saline to be pleasant for drinkin!1!
Lava, probably basaltic, covers the slopes and forms characteristic
flat-topped hills near by. The association of lava with thermal
carbonated water that deposits a notable amount of lime carbonate
seems to be exceptionally well shown at these springs. Their tempera-
tures have warranted their indication as thermal-carbonated springs
on Plate III (in pocket), but they are more noticeably carbonated
than thermal. The saline character of the water is also worthy of
note.
Marine beds of Cretaceous age have^been described by Diller 1 as
probably underlying the lava of this region, and it seems probable
that the salinity of the springs is derived from these sedimentary
beds. This same suggestion was advanced to account for the saline
character of Morgan Hot Springs, near Lassen Peak.
