‘rocks previously classified as older were found to contain fossils
definitely identifable as belonging to the Skeena formation. The
POPMREL OR DONS extends nearly to the top of the mountain in a
thin shell. On the western slope it likewise extends up the
mountain in a thin shell. A small mass occurs near the top of
Hunter mountain and other masses occur in Skeena valley near
Hazelton and on the slope of the mountain to the west. The Skeena
formation in all these localities is decidedly different from that
in the extensive low areas. The strata as previously noted by
Menon ere badly deformed and dip away from the peaks toward the

valleys. They are metamorphosed rocks which are indistinguishable
from older formations and include anthracite instead of bituminous
coal. On the west slope of Hudson Bay mountain the metamorphosed,
deformed rock can be followed and found to grade to the un-
metamorphosed and undeformed material. Similar stratigraphic
successions, the presence of coal, and gradations from one type
to another in many localities, as brought out by Leach, offer
proof that these metamorphosed masses have been correctly class-~ at
ified as Skeena formation.

Overlying the Mesozoic complex on Driftwood ercek and
possibly at other places in the region are Upper Hocene or
Oligocene souemenies including sandstone, shale, ccnglomerate,
lignitic coal, and some white, rhyolitie to glassy tuffs.
Younger Tertiary basalts and andesites which form a cliff 1,500
feet high south of Houston cover like a blanket an extensive

area southeast of this.
