+ The immediate neighborhood of
Camp Rochester is remarkable from
physical point of view. Within radius
of ten miles of this camp are several
extinct cinder cones of typical form,
marking the site Of as many volcanic
vents, which are the seats of the dying
volcanic activity which has in the past
been such a prominent characteristic
Of this portion of the desert. The old
est rocks Of the region are intrusive
diOrites and quartz porphyries, and
later, often everything these are rhyo-
( lites. rhyolite tuff and breccia, ande-
sites, etc, and still later the black oil
vine Dasalts, which, coming up through
the volcanic vents, spread over many
square miles of the country. The in
dicatiOns are that the most recent
eruptions were of quiet kind, in which
the lava rose in the craters and over
flowed, the molten rock extending in
some instances ten or twelve miles
from the craters. Later the cinder
cones were built up about the vents
and the internal fires slumbered. How
long these volcanoes have been silent
no one knows. but the lava looks.
