road northward from Quincy. One small carbonated spring here
forms a drinking pool at the upper edge of the road, and 20 yards
south of it, below the road, there is a second spring or group of springs.
At the latter place three small board-curbed basins have been made,
and the discharge was formerly piped to a bathhouse 30 yards far-
ther down a steep slope. When visited in 1909 this house had evi-
dently been unused for a considerable time, and a crumbly layer of
lime carbonate one-fourth of an inch thick had been deposited on
the floor by the overflow from the bath tub.
The carbonate deposit covers the surface from the springs west-
ward to the creek, a distance of 125 yards down the steep slope, and
forms a bluff for an equal distance along the stream. A few other
deposits of much smaller extent were observed on the western side
of the creek.

CARBONATED SPRINGS ON INDIAN CREEK (PLTTMAS 13).
About 1J miles in a direct line northward from the springs on
Spanish Creek that have just been described, carbonated springs
issue on the southeastern side of Indian Creek, near a deposit of
lime carbonate formed between the road and the creek. This
deposit is larger than that at the other locality, for it covers an
area of approximately 200 by 400 yards and forms a steep slope for
a quarter of a mile along the creek. Plate IX, B (p. 134), shows a
lower portion of this deposit. The carbonate deposit extends north-
ward parallel to a bend of the creek at this locality and makes a
low ridge that slopes northward to the stream. Along the crest of
this ridge there are three depressions or sinks, 5 to 30 yards in
diameter, in which a hard compact lime carbonate is exposed which
resembles that of the "hoodoos" near Mam moth Hot Springs in
Yellowstone Park. In the southernmost sink, which is the largest,
two mounds of the more common white lime carbonate have been
formed, and small pools of carbonated water of seeping flow still
exist on their tops. Small veins of calcite and of banded onyx mar-
ble were also noticed in the darker, more massive carbonate in this
sink. The more recent surficial deposits on the lower slopes are of
the usual white carbonate. At the southern edge of the deposit, a
few yards below the road, two pools form drinking springs, and the
water has also been taken away in bottles for its supposed medicinal
value. It is moderately carbonated, but it is too warm and too
saline and calcic to be a pleasant drinking water. These pools are
about 4 feet apart and are approximately a foot in diameter and a
foot deep. When visited they did not overflow and contained only
a few inches of water. On bailing out one the other was also emp-
tied, indicating that they are connected underground.
A few small springs were noticed at the northern end of the deposit
and also along its western side, bordering the creek, but only two of
