CARBONATED SPRINGS. 231
The spring was well known to the Indians and later to white set-
tlers, and formerly supplied a small drinking pool. As this pool
easily became roiled, however, a number of years ago a shaft was
sunk 13 feet deep to bedrock at the spring, and a joint of pipe was
cemented into the fissure from which the water came. The water
rises in this pipe to the surface clear and fresh and is used locally as a
table water. It was at one time bottled at the Oroville soda works.

SUMMIT SODA SPRINGS (PLACER 5).
A number of groups of small carbonated springs lie in the Sierra
west of Lake Tahoe. One of the northernmost of these groups has
long been known as Summit Soda Springs, although the springs are
about 13 miles by road south of Summit station, on the Southern
Pacific Railroad. The springs are situated in a little flat beside
North Fork of American River, and in the late eighties or early
nineties a hotel was built, and the place was conducted as a resort
for several years. The hotel burned in 1898, however, and since
then the property has not been open to the public.
Four cool carbonated springs rise in the flat on the south side of
North Fork, and a fifth rises at the edge of the stream. Three
of them have been inclosed by spring houses and are used as drinking
springs. All have small flows, but they are strongly carbonated and
deposit noticeable amounts of iron. The following analyses of one
of the principal springs shows the water to be moderately alkaline
and saline:
