Although the water is strongly mineralized, water from one of the
springs, which is said to contain 1 pound of solid matter in 17 gallons
(about 7,000 parts per million), was used without causing serious
trouble in the boiler of a hoisting engine at the quarry, by injecting
about a gill of kerosene a day.
The ridges seem to have been formed by deposition along the sides
of fissures, continuing until the opening was reduced to a mere crack
or was closed entirely.
The lava from which the two groups of springs near Bridgeport
rise possibly gives the water its thermal and also its chemical char-
acter. In regard to the latter character, the association of lava with
hot springs that deposit lime carbonate is here again to be noted.
WARM SPRINGS BETWEEN BRIDGEPORT AND BO DEE (MONO 5).
In the mountainous region between Bridgeport and Bodie ther-
mal water rises in Warm Spring Flat, but no information is at hand
concerning either its temperature or its discharge. The springs are
thought to be relatively small and unimportant, however, and they
are probably used only as watering places for range stock.
Another warm spring issues near Mormon Creek, 1^ miles south-
east of Warm Spring Flat. It is worthy of note that Fales Hot
Springs (Mono 1), the hot springs near Bridgeport (Mono 3), and
the springs in Warm Spring Flat and on Mormon Creek lie in a direct
