ravine, 250 feet above the road. A cemented reservoir in the ravine
collects the water, which has been piped to a storage tank at the road1
side, whence it has been taken to San Diego and bottled as a table
water. The spring seems to be of seepage flow and of essentially
surface origin.
CORONA SPRING (SAN DIEGO 5).

A number of cold springs of excellent water rise along the southern
border of Warner Valley, which is in the mountains about 60 miles
by road northeast of San Diego. One of these springs was developed
commercially a few years ago, and its water was placed on the local
market as a lithia table water. The following analysis shows that
it is a slightly mineralized water, primary alkaline and saline and
secondary alkaline in character. The rather large proportion of
lithium reported is noteworthy.

In 1908 the water rose in a small cemented basin at the base of a
15-foot bank of black alluvium in the first ravine east of the road
grade from Mesa Grande northward down into Warner Valley. A
scum of brown iron-colored deposit, probably the vegetable growth
known as Crenothrix, covered the surface of the water, and a few large
bubbles rose in the basin. A pipe extended thence 200 yards down
the ravine to the valley edge, where the water had been run into
tanks and taken to San Diego for bottling. The water at the lower
end of the pipe had a distinctly sulphureted odor. The discharge of
the spring was approximately 30 gallons a minute.
