60 SPRINGS OP CALIFORNIA.
At the main springs, where the temperature of the water was 110°
to 140°, the material was mainly fibrous and white, green, and
reddish-brown in color.
About 75 yards below, at a temperature of 96°, there was a dark-
green layer on the bottoms of pools, with a small amount of white
material on the surface of the green. Where the current was swift-
est, a purple-brown, furry growth, one-eighth to one-quarter inch
thick, covered the rocks.
At 125 yards, where the temperature was 91°, a green, leathery
growth covered portions of the bottom, with white, feathery stream-
ers attached to it where the current was rapid.
At 200 yards, in a temperature of 87°, a thick, leathery growth
coated the entire stream channel, being green and white on its upper
surface, pale purplish-red inside, and black on the under surface. A
number of pale purple, feathery, and white threadlike streamers ex-
tended from it.
At 250 yards, in a temperature of 83°, there was a layer of green
material in the pools and white material in the swifter water.
At 275 yards, where the temperatupe was 81°, the lower limit of
white growths was reached. Below it a dark-green moss coated the
rocks for a distance of about 50 yards to a point where the tempera-
ture was 78°. Below this point there was no notable growth in the
channel.
The material showed a tendency toward brighter colors in the hot-
ter water and more somber ones in the cooler places. White material
(probably due to the deposition of sulphur) was more common in the
hottest water and in the portions of the algous growth nearest the
bottom of the channel. Smooth, leathery growths lined the pools,
while fibrous growths were formed in the swiftest currents. The
discharge of the stream was approximately 100 gallons a minute.
The water first rose at a point about 50 yards above the main springs.
Above this point the stream channel was dry.
PARAISO HOT SPRINGS (MONTEREY 2).
Paraiso Hot Springs (PI. IV, 0, p. 32) are situated near the head of
a small valley that opens eastward to Salinas Valley. Underground
water lies at a shallow depth near the springs, beneath an area of
several acres within which at least five mineral springs rise. The
largest of these, which is known as the Soda Spring, has an observed
temperature of 111° and a discharge of perhaps 8 gallons a minute.
About 40 yards away two small sulphur springs rise with tempera-
tures of 88° and 102°, and 100 yards farther east there are .two
drinking springs, each of which yields perhaps one-fourth gallon a
minute. These are known as the Iron Spring and the Arsenic Spring
and have temperatures respectively of 68° and 65°.
