Geocache Description: Elk Run Shaft is a memorial built on the air shaft of The Rolling Mill Mine. On July 10, 1902 a gas and dust explosion rocked the mine causing th death of many miners. Early reports state that only 4 miners were brought alive and that very few miners were killed by the blast, the rest were killed by "afterdamp", a poisonous mixture of gasses formed by the blast. The mine did reopen producing approx. 22 1/2 million tons of coal until it was closed in 1931. The mine was owned by The Cambria Iron Works at the time of the blast. The president was Powell Stackhouse. The final coordinates are N40 link W078 link Where A=The third digit in the number of miners killed.
