Softening temperature of ash for each sample as received were: No. 1,
2,290°F., No. 2, 2,140°F., and No. 3, 2,140°F. :
No. 1 is sample of 3 feet of coal on shore of river. Nos. 2 and 3 are

samples from trench on Galloway slope; No. 2 is of entire 3-9-foot seam and
No. 3 is of the lower 1-5 feet.

Variations in Seams in Peace River Canyon

In some coal sections, where samples have been taken from separate
benches, the ash is found to increase progressively upward in successive
benches. Examples are the Trojan seam on Coal Creek and at Contact
Point, the Falls seam on Gething Creek, and some of the sections sampled
of the Grant seam. Other coal sections show about equal ash content in
the upper and lower benches. Examples are: one of the Grant coal sections
at the west end of Grant Flat and the Galloway seam at Galloway Falls on
Gething Creek. One of the sections of the Grant seam examined has the
highest ash in the bottom bench. The amount of ash may also vary
laterally, but, in most of the examples noted, less than vertically. The per-
centage of ash in the bottom bench of the Grant seam varies from 2-1 to
3-4 in four sections, and is 6-1 in a fifth section sampled. The middle
bench varies, in three sections, from 2-6 to 2:9, and the top bench, in three
sections, varies from 4-1 to6-1. At three localities the Trojan seam varies
from 8-4 to 10-6 in percentage of ash, omitting the 6-1 ash content of the
lowest bench on Coal Creek. At Contact Point this seam is very high in
ash. The Trojan shows the highest lateral variation at present known for
any coal seam in this area. The following seams have a percentage of ash
below 5: Grant, Milligan, Mogul, Gething, Galloway, the 3-foot seam on
Johnson Creek, and the lower and middle benches of the Falls seam on
Gething Creek. The following seams vary in ash percentage from 5-5 to
7-4: the top bench of the Falls seam on Gething Creek, Riverside, lowest
bench of the Trojan seam on Coal Creek, and the 4-foot seam on Johnson
Creek. The following vary in ash from 8-4 to 11:2 per cent: Trojan seam
on main Gething Creek and on the north branch of Gething Creck, Little
Mogul, upper benches of the Trojan seam on Coal Creek, and the lower
part of the Trojan seam at Contact Point. The upper part of the Trojan
seam at Contact Point and the topmost 43-inch bench of canneloid coal in
the Trojan seam on Johnson Creek vary from 16-1 to 21-5 per cent ash.

The Peace River Canyon coals vary in rank from medium to low
volatile bituminous. The variation does not appear to be related to geo-
graphic position in the area nor to proximity to rolls or other structural
features. Rather, the variation is with the seam and with the bench within
the seam.

Most of the coal in Peace River Canyon is non-agglomerate, or just
agglomerate, with very few samples showing good caking qualities. No
entire seam studied is caking throughout. ‘This quality is confined to a
bench within a seam, and, in all places so far studied in this area, to a lower
bench. The lowest 8- to 11-inch bench of the Grant seam is good caking.
On Coal Creek, the part of the lowest bench of the Trojan seam sampled
is also good caking. At Contact Point the lower part of the Trojan seam
is good caking, and the upper part agglomerates. In the west, on Gething
Creek and on the north branch of Gething Creek, the Trojan seam is non-
agglomerate.
