HOT SPRINGS. 127
AMEDEE HOT SPRINGS (LASSEN 17).
The second group of hot springs in Honey Lake Valley is about 5
miles southeast of Shaffer Hot Springs, near Amedee depot. The land
here is alluvial and slopes very gently westward toward Honey Lake.
Scalding water forms several groups of shallow pools, mainly at
six places in a belt about 600 yards long that trends nearly south-
ward, but one-third of a mile S. 30° W. (magnetic) from the southern-
most of these main groups another hot spring forms a pool in salt-
grass land, and hot water probably rises at other places still farther
toward the lake. Temperatures of 172° to 204° (practically the boil-
ing point at this elevation, 4,000 feet) were noted in the several
springs, and the total discharge of hot water as measured by the flow
of six run-off streams is about 700 gallons a minute.
In 1909 the springs had not been improved to great extent, but
there was a small bathhouse beside the railroad, near one of the
largest groups of springs. At the southernmost of the main groups
there was also an old bathhouse, and water from one of the northern-
most springs was used in preparing sheep dip. At the Amedee Hotel
a shallow well 80 yards east of the nearest springs supplied water at
a temperature of 134° for kitchen use.
There are no prominent deposits of tufa at Amedee, such as there
are near Shaffer Hot Springs, but near the southernmost of the main
groups tufa appears over a small area. The hottest spring rises from
this material. The following analysis of the water from this spring
shows that it is a primary saline water almost identical in character
with that of the Shaffer spring but of slightly less concentration.
