The Bowron River Coalfield

The Bowron River Coalfield (1:100,000) (PDF, 2.4MB)

An area of Tertiary coal-bearing rocks is preserved in a graben-like structure covering 47.5 square kilometres along the Bowron River south of the Yellowhead Highway. Three coal seams with a cumulative thickness of 8.5 metres are contained in the lower 75 metres of a 600 metre sedimentary section. The seams dip at 20° to 60° limiting any surface-mining potential. The deposit is noteworthy because it contains amber occurrences. There has been some underground exploration for coal and amber, but no mining. Coal rank is high-volatile C and B bituminous.
