HOT SPRINGS. 33
The springs form two groups situated about 400 yards apart. The
upper group comprises perhaps half a dozen springs whose observed
temperatures range from 110° to 145°. The water is confined in two
concrete storage basins that are in part the foundations of the original
bathhouse, and it is thence piped to the baths and to heating pipes
throughout the hotel, which is about 200 yards southwest of the
basins. The Palm Spring, on the mesa north of the hotel, is in this
group. The second group lies in a ravine to the west and also com-
prises about half a dozen springs. Water from one of these is pumped
to the storage basins at the upper group to augment the supply for
the hotel. The hottest water is in the spring known as El Penyugal,
in the lower group. This spring is surrounded by a concrete basin
and the water is used for drinking. A temperature of 187° was re-
corded in the basin and in sampling for one of the analyses the basin
was drained and a temperature of 202° registered. The spring dis-
charges perhaps 15 gallons a minute. Granite Spring is on the mesa
on the west side of Penyugal Canyon.
The total yield of the Arrowhead Hot Springs is hard to estimate,
but it is probably not far from 50 gallons a minute.
Water from a cool spring, Fuente Erio, situated about a quarter of
a mile north of the hotel, was placed on the local market as a table
water during 1909. Agua Fria is the water of Cold Canyon, at the
head of the pipe line leading to the main reservoir on the high mesa
north of the hotel. Analyses of several of the springs are given on
page 34.
WATERMAN HOT SPRINGS (SAN BERNARDINO 35).
About three-fourths mile west of Arrowhead Hot Springs smaller
hot springs rise from fissures in the granite on the eastern side of
Waterman Canyon. These springs have been used to some extent
for bathing, but when visited in 1908 the accommodations had evi-
dently not been kept in repair for several years and there was only a
slight flow of water from a small marshy area and a pool beneath a
bank at the creek side. An analysis of the water of the only spring
that has been walled in is tabulated with analyses of the Arrowhead
Hot Springs.
