ST. HELENA WHITE SULPHUR SPRINGS (NAPA 10).
St. Helena White Sulphur Springs are situated in the canyon of
Sulphur Creek, 2 miles southwest of the town of St. Helena. They
form the nucleus of an old and formerly a well-known resort, but
about 1904 the hotel was destroyed by fire, and in 1909 the improve-
ments had not been extensively rebuilt. There were, however,
cottages and an open screened dining room, furnishing accommoda-
tions for about 25 people, and a small bathhouse near one of the.
springs.

The group includes five noteworthy springs which issue within a
space of 150 yards near the foot of the slope 011 the northeast side of
Sulphur Creek. All these springs were formerly improved with
brick basins, but when visited the northern two were the ones chiefly
used. One of these formed a drinking pool that yielded about one-
half gallon a minute of mildly sulphureted water. The northern-
most spring, which is about 25 yards beyond the drinking spring,
was surrounded by a cement reservoir and yielded warm, mildly
