1. Hottest drinking spring; 2. Main bath spring.
The analyses represent primary saline waters of the chloride type,
the drinking spring being characterized by secondary salinity and ths
bath spring by secondary alkalinity. Tertiary alkalinity is not fully
reported. The presence of berates in both springs is noteworthy.
Along this portion of its course Klamath River has cut a wide
canyon, 1,200 feet or more deep, into lava. Prominent bluffs of
tuffaceous material are exposed along its north side one-third of a
mile west of the Klamath springs. Faulting might again be appealed
to in an attempt to explain the rise of the thermal water here, but it
is possible that an abnormal temperature gradient in the bottom
of this deep canyon in the lavas, combined with local fracturing or
with the presence of porous beds that allow the escape of deep-seated
water, may furnish a satisfactory explanation for the existence of the
hot springs.
HOT SPRINGS ON BID WELL CREEK (MODOC 10).
In the western part of the United States there is a large area from
which no streams flow to the ocean and which is therefore called the
Great Basin. Many of the mountain ranges and intervening valleys
in this area have been formed by extensive faulting, a mode of forma-
tion here so common that its result is known as "Basin Range"
structure. One of the minor divisions of the Great Basin along the
northeast border of California is Surprise Valley, whose formation
