108 SPRINGS OF CALIFORNIA.

CALISTOGA HOT SPRINGS (NAPA 4).
At Calistoga,1 near the head of Nap a Valley, are several hot springs
at which during the seventies there was a large resort. The hotel
burned in the late seventies or early eighties, however, and since that
time the springs have not been of more than local importance. In
1910 the caretaker of the property had provided two bathhouses of two
tubs each, half a dozen small cottages on the place were rented, and a
few campers had pitched their tents near by. Hand pumps supplied
hot water directly to the tubs, and cool water was piped from a tank.
Four main springs rise at the base of a knoll of buff-colored tuffa-
ceous material at the northern border of the meadow land, and a few
pools and seepages of hot water appear in the meadow itself. The
observed temperatures of the principal springs range from 126° to
173° and their flows from about one-fourth gallon to 5 gallons a
minute. The hottest spring, which yields about 1 gallon a minute,
appears to be the most strongly mineralized, though its mineraliza-
tion is only slightly perceptible to the taste. Algse probably give it
the slight flavor that has caused it to be called a chicken-soup spring.
At Calistoga Hotel, about 400 yards west from the springs, a dug
well supplies warm water for tub baths and a swimming plunge.
Warm water is also obtained in several other wells near by and there
is one strongly flowing artesian well. The following analyses show
that the waters are primary saline in character:

1, Spring near creek; 2, swimming pool; 3, well at Calistoga Hotel.
i This name is said to be formed from the words California and Saratoga, but the springs are not at all like
those of Saratoga Springs in New York.
