1 From Mathews (1947).

“Analyses of coal samples from the map-area indicate that several of
the seams contain less than 5 per cent ash and, in this respect, compare
very favourably with coals from other North American fields. The calorific
value is high, being more than 13,000 B.T.U.’s per pound for many seams,
even in surface samples, and the calorific value of nearly all coal samples
computed on an ash-free moisture-free basis exceeds 14,000 B.T.U.’s per
pound. The carbon ratio, that is the ratio of the content of fixed carbon
to volatile combustible matter, ranges from 1-7 to 4-7 and averages about
2-5. Most of the coal can be considered as medium-volatile bituminous
according to the classification by rank as proposed by a committee of the
