1t must not be presumed that these

and trembling ON the surface, the
thing we interpret as an earthquake.
The rocks found in the area are
representative of the early geological
ages, from Cambrian to Pennsylvania,
inclusive. The Cambrian is repre-
scented by the dark heavy quartzite
found at the base of the mountains.
In the mouth of the Box Elder Canyon
these have been reduced to schists.
The Ordovicoan and Silurian have
never been differentiated but they
are found as blush gray lime stone
with layers of shale
and quartzite. These outcrop near the
base of the mountains on the east
sides. The heavy lodges farther up
on the mountains are NIississippian
These contain abundance of fossils.
Above the thick heavy lodges is the
thin bedded blush gray limestone
which belong to the carboniferous.

gave rise to the Irregularities, depres-
