The Rossland Mines
You have entered the crater of an ancient volcano rich in minerals. The waste dumps are the remains of famous Rossland mines staked in 1890 by prospectors passing on the nearby Dewdney Trail. From these fabulously rich workings came 6,000,000 tons of ore worth $125,000,000. The City of Rossland and the huge smelter at Trail were born of these mines.
