These Mio-Pliocene
Hole-in-the-Wall conglomerates and sandstones
accumulated
along the active segment of the Furnace Creek basin.
The
Hole-in-the-Wall member is part of a fan delta complex originating
from the
Funeral Mountains, depositing into (the now dry) Lake Zabriskie.
Sedimentation
in this area was greatly influenced from the strong dip-slip
movement
of the Furnace Creek fault. This is a
good location to exercise the
clues in paleo “up” directions. Grain size grades from large cobbles to sand
sized grains in
short episodes, which gives us the impression that deposition
was very rapid and happened many times in this area.

rock’s surface.
