CARBONATED SPRINGS. 243
Although a number of other carbonated springs in this region are
also above a normal temperature, the unusually high temperature
of this spring is especially worthy of note, and it is therefore indicated
on Plate III (in pocket) as a thermal carbonated spring. The spring
rises near the trail at the stream crossing, so it is used to some
extent for drinking. The rock near it, as elsewhere along the canyon,
is granitic.
CARBONATED SPRING ON SODA CHEEK (TTTLARE 12).
About !-§ miles above the spring just described (Tulare 11) there
is a carbonated spring on Soda Creek 150 yards above the trail. The
spring issues among granitic bowlders at the eastern side of the stream
channel. Like the springs farther downstream, it is strongly carbon-
ated, tastes sweetish, and deposits iron, but a noticeable amount of
lime carbonate was not seen. The spring is visited to some extent
for drinking water.

NELSON SODA SPRINGS (TULARE 13).
Nelson Soda Springs, or Camp Nelson, as the place is better known,
is a mountain resort 15 miles east of Springville and near South Fork
of Middle Fork of Tule River, also called the East Fork of Middle
Fork.
Four carbonated springs rise on the property. The lowest spring
is on the southern bank of the stream, one-quarter of a mile west
of south from the resort. It issues beneath an overhanging bank,
in a small natural grotto of lime carbonate (PI. XIII, C] and flows
over an iron-stained terrace of the same material. The spring yields
approximately 8 gallons a minute of strongly carbonated water, but
it is too warm (69°) to be palatable. A second spring rises one-third
of a mile southeast of the resort about 50 feet above and 50 yards
from the north side of the river. It forms a small, rock-walled pool
that yields about 4 gallons a minute of carbonated water 63° in tem-
perature. It has deposited only a small amount of lime carbonate,
but it has deeply iron stained its run-off channel. About 75 yards
east of the spring just described another carbonated spring of nearly
the same discharge issues on a low bank near the river in a deposit
of lime carbonate that borders the stream for 200 yards. Two-fifths
of a mile farther east a fourth spring rises in a little meadow. It
yields about 8 gallons a minute of effervescing carbonated water that
is fairly cool (62°) and is the most palatable of the four.
The springs rise in a region of granitic rock, but on the slopes above
them are ledges of limestone that may account for the apparent high
amount of calcium in their waters.
Limestone appears, possibly as included masses in the granitic rock,
at a number of other places in this part of the Sierra. Although its
