feet thick in one exposure, appear to correspond to two seams, each 1 foot
thick, only 1,000 feet away, but their correlation remains uncertain, due
to the possibility of a fault in this locality.

W. H. Mathews (1947) collected a large number of samples of coal
from the Carbon Creek coal basin and he arranged the analyses of these
samples into two convenient tables, which are reproduced here (See
Tables IV, V). The following excerpts describe the localities from which
the samples listed in Table IV were collected, and Figure 16 is a reproduc-
tion from Mathews’ report to show the localities from which the samples
listed in Table V were collected.

“The lowest of the thicker coal-seams known to occur in the northern
part of the Carbon Creek basin is exposed on a small creek which enters
Carbon Creek from the west, 5 miles above the Peace River. This seam
lies about a quarter of a mile west of Carbon Creek and is about 1,000 feet
above the base of the coal-measures. Its thickness is 2 feet 11 inches. An
analysis (No. 1) of a sample from this exposure is given in Table 1 [IV].

“Four seams are believed to be present near the junction of Carbon
Creek and Seven Creek. The lowest of these seams, about 5 feet in thick-
ness, is exposed on Seven Creek 2-2 miles from its mouth, and apparently
also on a creek joining Carbon Creek from the east a few hundred yards
above Seven Creek. This seam may also correspond to the one described
by Galloway as occurring on Carbon Creek itself about half a mile below
Seven Creek, but which could not be found by the writer. Analyses
(Nos. 2, 3, and 4 respectively) of samples from these exposures are given in
Table 1[IV]. This seam lies about 2,000 feet above the base of the coal-
measures. The second seam, some 3 feet in thickness, lying approximately
25 feet above the first, is exposed on Seven Creek about 1-5 miles above its
mouth, and apparently also on Carbon Creek opposite the mouth of Seven
Creek (Analyses 5 and 6, Table 1 [IV]). The third seam, 2 feet 4 inches
thick, about 150 feet above the second, and a fourth seam, 2 feet 2 inches
thick, 20 feet above the third, are exposed on Seven Creek 1-5 miles from
its mouth (Analyses 7 and 8, Table I[IV]).

“No other seams are known to occur in the northern part of the basin
between these four seams and the seam 3,000 to 4,000 feet above the base
of the coal-measures, exposed on Nine Creek 1-2 miles from its mouth.
The latter seam is described by J. D. Galloway as being 5 feet 4 inches
thick, exclusive of a 2-inch shale parting 10 inches from the base of the seam
(Analysis 9, Table 1 [IV]). In 1944 and 1945 the lower part of this seam
was inaccessible, and only the upper 4 feet 2 inches could be sampled
(Analysis 10, Table 1 [IV]). This seam may correspond to the lowest seam,
about 6 feet thick, exposed in the canyons of Eleven Creek.

“A seam 2 feet 7 inches thick, probably less than 1,000 feet above the
base of the coal-measures, exposed in the western part of the basin on Eleven
Creek 5 miles from its mouth (Analysis 11, Table 1 [IV]) cannot be correlated
certainly with any of those described above.

“Several seams in the lower part of the coal-measures in the southern
part of the basin outcrop on McAllister Creek and on a tributary entering
it 2-8 miles above its junction with Carbon Creek. An exposure of one seam
on the latter tributary 1 mile above McAllister Creek, possibly 1,000 feet
above the base of the coal-measures, is 8 feet 9 inches thick, but has probably
