238 SPRINGS OF CALIFORNIA.
The springs have been used mainly for drinking by campers and
travelers through this portion of the mountains, but they form one of
the best-known groups of carbonated springs in the Sierra. The
water has occasionally been used in making biscuits without the use of
baking powder, as the carbon dioxide in the water serves to lighten
them.
The region is one of massive granitic rock, where domes and sharp
spires are common weathering forms of the coarse-textured material.
CARBONATED SPRING AT HEAD OF AGNEW MEADOWS (MADERA 3).

A number of small carbonated springs are situated in the drainage
basin of the northern branches of San Joaquin River, which lies south-
ward across the divide from the headwaters of Tuolumne River. The
springs are rather isolated from one another, but several of them are
near trails through this rugged section of the mountains and are becom-
ing well known as drinking springs to the rapidly increasing number
of people who appreciate the grandeur of the high Sierra and visit
them during the summer.
At the northern end of Agnew Meadows, about 20 miles in a direct
line (or 28 miles by road and trail) southeast from Lambert Soda
Springs, there is a low, iron-stained mound of lime carbonate near
some prospect dumps. Very little water issues here now, but the
alkaline deposits are said to be used by deer as a salt lick.

CARBONATED SPRING NEAR PUMICE FLAT (MADERA 4).

A carbonated spring that is often visited by travelers is situated
about 44 miles by trail southward from the spring at the head of
Agnew Meadows and one-fifth of a mile from the main trail in Pumice
Flat, northwestward up the eastern side of Middle Fork of San Joaquin
River. A cool, rather stagnant pool, a yard in diameter, lies 30
yards from the stream, on a gentle slope that is covered with pumice
gravel. Across the stream there is a bluff of dark lava agglomerate.
The water is strongly carbonated, and considerable iron is deposited
along its seepage overflow. Near the river's edge, 50 or 75 yards west-
ward, there are several small pools that are slightly carbonated, but
they seem to be supplied mainly by seepage water from the river.
There is said to be another small carbonated spring a quarter of
a mile farther upstream, however.

CARBONATED SPRING ON MINARET CREEK (MADERA 2).
A small but strongly carbonated spring lies in the canyon of Minaret
Creek, about 5 miles westward by trail from the spring near Pumice
Flat. In 1909 a well-traveled trail had not been opened along Minaret
Creek, however, and the spring had been seldom visited.
