In 1889, a mine collapse allowed water in an adjacent abandoned and flooded mine to rush into the White Ash mine, drowning the 10 men working in this mine. The mine was closed and abandoned following the flood, entombing the bodies.

The White Ash coal mine extended underground from what is now the athletic fields of the Colorado School of Mines northward to a point about 1 mile north of Clear Creek.
