the state of the geophysical industry
today? Still breathing, but still hurting.
geophysical industry is facing a host
of environmental and safety issues that threaten all seismic operations.

Whatever the challenge, the geophysical technology needed for the

view looking west along Alaska's Atigun River in Atigun Gorge, about
130 miles south of Prudhoe Bay and 100 miles southeast of Umiat
(nearest corner of the National Petroleum Reserve-Alaska). The dark-colored
slope behind the helicopter exposes the contact between shales of
the Torok Formation (low on the slope) and overlying sandstones
of the Fortress Mountain Formation, both Lower Cretaceous in age.
The sandstones here are shallow marine to deltaic facies, and are
lightly oil stained. Dark-colored rocks along river are intensely
deformed Permian to Lower Cretaceous rocks of the Siksikpuk and
Okpikruak formations. Mountains in background are mostly carbonates
of Carboniferous-aged Lisburne Group. These exposures provide important
constraints on stratigraphic and structural relations that are important
to assessment of oil and gas potential in the NPR-A.
