Glace Bay is located on a seam of soft coal that, if followed, would run from New Brunswick, under the Bay of Fundy, beneath the Nova Scotia peninsula and island of Cape Breton (where it surfaces at Glace Bay, near Sydney Mines, at the northeastern end of the island, and then contunues under the bed of Saint Lawrence Bay all the way to Newfoundland.

Notice the natural arch the waves have carved through the coal seam.

A fascinating, and harrowing, story about coal mining under the "old" system, tantamount to serfdom, was told to us first-hand experience by our guide.
