202 SPRINGS OF CALIFORNIA.
NEWMAN SPRINGS (LAKE 8).
Newman Springs are about If miles north of west from Bartlett
Springs (Lake 9, p. 200), and issue along the channel of Soap Creek;
hence they are sometimes referred to as the Soap Creek Springs. The
spring farthest downstream which is the principal one emerges at
the creek side at the base of a prominent ledge of serpentine that
forms the eastern border of a belt of this rock and the contact zone
between it and crumpled shales and siliceous sediments that continue
eastward. The spring yields about 15 gallons a minute of mildly
carbonated water 86° in temperature, that is turbid with iron. The
water is conducted across the creek in a trough to a small plunge bath-
house. A spring in the creek bed about 75 yards above (southwest of)
the main spring, forms the Borax Pool, which contains warm, turbid
water that is considered to be of exceptional value for bathing. The
serpentine belt continues for about 100 yards upstream (westward)
from it and is then succeeded by schistose rock, from which seepages
and slight flows of warm carbonated water issue in at least seven places
along a distance of about 275 yards or to a point about a quarter of a
mile above the main spring. Temperatures of 72° to 92° were
noted in these small springs, and the locality is therefore indicated
in Plate III (in pocket) as containing thermal carbonated springs.
The position of the springs with respect to the serpentine dike is sug-
gestive in considering their origin, for this dike may not only afford
an upward passage of escape for heated water but may possibly also
be the direct cause of its abnormal temperature.
HAZEL SPRINGS (LAKE 7).

About 8 miles northeast of Upper Lake, at Hazel Springs (formerly
known as Dennison Springs), two small carbonated springs issue
about 20 yards apart. The property has been used at times as a
summer camping resort, but during July, 1910, it was closed to the
public
ROYAL SPRING (LAKE 6).

Royal Spring is about 7 miles west of north from Bartlett Springs
(Lake 9, p. 200), and 2 miles by a slightly used road running north from
the dairy ranch in Twin Valley. The spring emerges on the side of a
ravine that is tributary to North Fork of Cache Creek. It has been
protected by a cement basin in which the water rises clear, but it
deposits some iron along its overflow channel. It is cool, moderately
carbonated, and tastes distinctly of iron or magnesia. In former
years, when the property was occupied, the spring was better known,
but it has been used for several summers as a private camping ground
only.
