rather than from constituents in deep-seated hot water that may
enter the alluvium.
FAIRVIEW HOT SPRING (ORANGE 1).

A warm spring or well at Fairview Hot Spring, in the coastal plain
south of Santa Ana, resembles in occurrence the Harlem and Urbita
springs. Originally the Fairview Spring was a natural flow, but a
casing that was sunk to a depth of 700 feet into it has converted
it into a flowing artesian well. In 1908 a hotel and cottages pro-
vided accommodations for about 50 people. The water rises with a
temperature of 96° and supplies a swimming plunge and tub baths.
The discharge varies somewhat with the season; in December, 1908,
it was about 15 gallons a minute. An odorless, inflammable gas rises
with the water and is burned for cooking and lighting. The water,
which is colored brown, doubtless from organic stain, has been placed
on the local market for table use under the label "Amberis Water."
Although the water has a faint oily taste, it is thought to be essen-
tially ground water that here rises through the deep alluvium which
forms this part of the coastal plain. Its origin is probably not re-
lated to the shales of the oil-bearing series of southern California that
form low hills a mile southward, except as these shales act as an
underground dam that forces the alluvial water of the artesian basin
of this region to the surface.

EDEN HOT SPRINGS (RIVERSIDE 8).
Along the western base of San Jacinto Mountains are several hot
springs that have already been mentioned in their relation to the
San Jacinto fault. At Eden Hot Springs, the northernmost group
along this fault, about eight small springs rise within a distance of
100 yards at the base of a steep granitic slope. The water issues less
than 200 yards beyond the southeastern border of a series of shales
and sandstones of Tertiary age, in which there are dislocations that
were probably caused by the uplift of the San Jacinto Range; but the
springs seem not to be related causally to the sediments. The max-
imum temperature of the water is about 110°. It is moderately
sulphureted but does not seem to be otherwise notably mineralized.
During 1909 water from two of the springs was placed on the local
market for table use under the labels "Iron Lithia" and "White
Sulphur."
A small resort has been maintained at the place for a number of
years. In 1908 cottages and tents provided accommodations for
about 50 people, and a bathhouse and small swimming pool allowed
use of the water for bathing.
