also piped to a bottling house below the hotel. It is used on the
grounds only for drinking and is bottled for table use. The water is
cool a temperature of 46° being recorded in the spring in January,
1910, but it is probably about 55° in summer and the yield is per-
haps one-half gallon a minute. It is strongly carbonated. and has a
petroleum odor and taste similar to th^t which was noticed at Skaggs,
Gordon, and Seigler springs. The analyses on page 189 show it is
a secondary alkaline water with notable primary alkalinity and high
tertiary alkalinity.
A smaller spring, the water of which is similar in character to that
o'f the main one, issues from the bank opposite the latter but has not
received much attention.
The rocks exposed along the ravine are sandstones and shales
which dip steeply, but the structure shown is probably to a large
extent of landslide character. On the higher slopes near the springs
these sediments are overlain by basaltic or andesitic lava.
BONANZA SPRINGS (LAKE 50).
Bonanza Springs are situated in a grove on a gentle slope border-
ing a ravine, about 3 miles north of east from Adams Springs, and
halfway between Seigler and Howard springs (described among the
hot springs, pp. 95-98). The property has been a camping resort for
a number of years. In 1910 there were 8 or 10 small cottages and
grounds for tents near by.
Three springs, which are known as Sulphur, Soda, and Iron, are
situated on the property. The Sulphur Spring is in a covered wellr
9 feet deep, from which a pipe extends a few yards northeastward
down the slope to a latticed house, where the water issues from a
small jet. This water is cool and noticeably sulphureted and also
has a slight oily odor and taste. An oily film is said to form on the
water of a shallow well near by. The Soda and the Iron springs
issue a few feet apart from crevices in a small exposure of sandstone
60 yards below the Sulphur Spring house. Both are cool and car-
bonated and have stained their basins with iron, though the Iron
Spring has done so to the greater extent. All three springs are small,
yielding only one-quarter to one-half gallon a minute each.
The rock at this locality seems to be sandstone, but on the slopes
a short distance above it is overlain by lava.
SPIERS SPRINGS (LAKE 52).
Spiers Springs are situated about 3 miles in a direct line southeast
of Bonanza Springs, in the canyon of the main branch of Putah
Creek.
Two springs of similar character issue a few yards apart at this
place and each discharges 7 or 8 gallons a minute. The water is
moderately carbonated and is noticeably sweet, probably from mag-
