through a low alluvial plain without touching the bordering highlands
or mountains. Above the mouth of the Omenica the banks increase
in height, and where cut into by the stream, show glacial sands, gravels
and clays, holding numerous scratched and polished boulders.

A mile and a half below Fort Grahaine, an exposure of hard grayish
contorted limestone appears on the west bank of the river, underlying
mica-schists and gneisses. The limestone strikes N. 40° W., and dips
to the west at an angle of 70” or over.

An examination was made of the mountains bordering the valley in Terraces.
the vicinity of Fort Grahame. The valley here has a width of about
five miles and is terraced on both sides of the river. The main ter-
race has a height above the stream of 175 feet. The other terraces,
although plainly visible from a distance, could not be distinguished
during the ascent. Water-worn pebbles were found up to a height of
over 2000 feet above the river.

The rocks observed consisted of lustrous mica-schists, mica-gneisses, Rocks in
and hornblende-schists, bedded diorites, quartzites, and occasional pe oe
bands of whitish crystalline limestone, all belonging to the Shuswap hame,
series.

At the base of the mountains the rocks dip to the south-west, at a
high angle, but further up the dip diminishes and at the summit the
beds are nearly horizontal. The strike is approximately N. 40 W., or
parallel to the direction of the valley.

The mountain west of the valley was ascended by Mr. Russel and
are reported by him to consist of mica-schists, gneisses and limestones,
similar to those east of the valley, dipping at high angles.

No glacial striz or grooves were noticed on either slope, but the Absence of
rocks in places appeared to have been smoothed and rounded by ice s!@ci#l strie.
moving in a south-easterly direction. From Fort Grahame to the
mouth of the Ingenica, a distance of about twenty miles, no exposures
were noticed along the valley. The bordering mountain ranges, judg-
ing by the material brought down by numerous tributary streams, are
built mainly of gneiss and mica-schists. The latter outcrops ina
couple of places a short distance above the mouth of the Ingenic:.

Six miles above the mouth of the Ingenica, plant-bearing conglom-
erates and sandstones of Laramie age appear in the valley. These
beds are similar in character to those in the Omenica, previously de-
scribed. They appear to be confined entirely to the great valleys of the
district and to be absent from the highlands, and if ever deposited on
the latter have been entirely swept away. They rest partly on an
