The above ection ‘is underlain by an additional 490 feet of
poorly exposed beds. These include brown weathering: sandstones
and shales and, in turn, are underlain by about 30 feet of light
grey, hard, medium-grained ‘sandstones that are coarser and more
massive than those in the upper part of the formation. These
sandstones may represent basal beds of the Gething formation.
The total thickness of the Gething, as derived from these measure-
ments, is 1,074. feet, and’ this is probably a minimum figure as
the base of the- formation is not known definitely. . The measure-
ments were made across the steeply dipping east limb of an anti-
cline where there is PUSS, to be “appreciable thinning in the beds.

A 5O- foot hee of - coarse- grained, light grey sandstone, with
chert-pebble conglomerate lenses, is exposed.on, Willow Creek and
may underlie the Gethings It is overlain, above the falls, by
100 feet of beds that include fine- grainéd ‘sandstone, siltstone,
shales, and coal.: The coal is representéd by three. seams
varying from 2 to -3 feet in thicknéss and three others between
3 and 11 inches thick. In tracing beds along their strike an
appreciable variation was noted in the. thickness of concretionary
bands in the shales Gas of partings in, the coal seams.

Moosebar Formation

The type section of the Moosebar formation was described by
MeLearn (1922) from a locality near Contact Point in Peace River
Canyon. Strata that are in part correlative with the Moosebar
underlie a large part of the present area. Fairly continuous
exposures occur-on Grizzly Creek; on the west fork of Johnson
Creek; on- Falling: Creek; and on’ the north’ fork of Falling Creek,
Outcrops are not abundant elsewhere and sections exposed are
generally less than- 50 Feet WiLL: | 4

Fossils EN aE ea of several genera of marine ‘pelecypods

“may be found throughout the sandstone and shale members of the

Moosebar formation. Though of no diagnostic value, they are
useful in establishing the correlation of isolated exposures as
