i, overburden was too thick to permit determination of the thickness
of the coal seams in the other pits. The thickness of the coal
in Pit No. 1, its stratigraphic position. and the structural
data, indicate that the coal probably represents the Discovery
seam. At the second locality, a 15-foot seam of sheared coal
occurs about 500 feet south of the Moosebar-Gething contact. The
strata between the contact and the coal outcrop dip steeply and
exhibit isoclinal folding with minor faulting. Additional pros-
pecting and trenching along the creek section are necessary before
it is possible to determine whether this coal section is the
continuation of the Discovery seam.

Insufficient development work has as yet been done to permit
definite correlation of coal seams and the calculation of
tonnages throughout the area. Locai faults and changes in
physical character of the coal in the folded zone might reduce
estimates of mineable coal considerably. An approximation of the
tonnage of coal in the Discovery seam on the east limb of the
anticlinal structure has been made, assuming continuity between
the adit and Pit No. 1. This region contains 400,000 tons of
coal above Hasler Creek level, using a 7-foot mineable section as
the average thickness. If the Discovery seam is continuous to the
second locality on Grizzly Creek, the available tonnage on the
east limb would be 1,200,000 tons. - Further prospecting should
reveal the Discovery seam on the west limb of the anticline, from
which additional tonnage would be available.

Other Coal Occurrences

Coal outcrops were observed at several localities in the
Willow Creek area. The overburden there is too thick to permit
tracing seams for any distance, and in most instances insufficient
data are available to-determine -the stratigraphic position of the
seams. On a westerly branch of Johnson Creek, a coal outcrop
over 7 feet thick occurs near the top of the Gething formation.
Several c- to 3-foot seams outcrop on Willow Creek, above the
first falls, near the base of the Gething. - South of Pine River
a 5-fcot seam and a 5-foot seam occur in the upper part of the
formation, but their exact stratigraphic position could not be
determined. Coal outcrops and thicknesses of individual seams
are indicated on the accompanying geological map:

Prospecting for coal in this area should be confined mainly
to a relatively narrow peltnear the contact between the Gething
and Moosebar formations. This is the stratigraphic horizon in
which the thickest coal seam is known to occur on Hasler and
Johnson Creeks. The most accessible region for prospecting and
development is east of Willow Creek on the south side of Pine
River and just west of Crassier Creek on the north side of the
PAVE TAS

_Oi1 and Gas Possibilities _

Exploration for oil and gas in the map-area would be confined
to drilling tests of strata below the Gething formation. No
detailed stratigraphic studies of the underlying formations have
been made in the Pine River region, and there is no information
regarding the presence of porous and permeable reservoir beds.

The Hasler and Willow Creek folds extend beyond the limits of the
area mapped so that it was not possible to determine the closure

on the structures. Further information on this and other factors
is necessary before the merits of the structures can be appraised.
