The Groundhog coalfield
In the Skeena Ranges of northwestern British Columbia, the Groundhog coalﬁeld defines an ovoid (30 x 80 km) area extending southeastwards from the headwaters of the Klappan and Little Klappan rivers to Groundhog Mountain. Coal occurs in several units of the Bowser Lake Group, which consists of Jurassic and early Cretaceous marine and non-marine strata deposited in Bowser Basin. The Groundhog coalfield contains the only significant occurrences of anthracite in Canada. Anthracite is relatively rare, making up about 1% of all coals globally. Of all coals, anthracite has the highest heat content per unit weight. The most significant market for anthracite is as PCI (pulverized coal injection) coal, which is used in making steel.
