The rock that is exposed along the road from the river to a place
350 yards southeast of the spring is dark-colored lava, but at this
place a green diabase is exposed, which forms a bank that extends
below the road to the spring and for some distance beyond. At the
roadside 200 yards southeast of the spring there are also small car-
bonated seepages from this rock.
CARBONATED SPRING ON SODA CREEK (SHASTA 3).
At the north side of Soda Creek, 1^ miles above Castle Crag Spring,
a small carbonated spring issues in a little pool in the stream gravel,
between two bowlders of the green diabase, which persists at least
this far up the canyon.
The water is clear and moderately carbonated and deposits small
amounts of lime carbonate and iron. Along the bank of the creek,
about 150 yards below the spring, a lime carbonate deposit is exposed
for a few yards.
The spring has not been improved, but it has been visited by picnic
parties. It is also used as a roadside drinking spring, as it is only 50
yards from an automobile road that follows the canyon of Soda
Creek.
