Abstract
The Red Marble Quarry is located near Chewelah, Washington within the Huckleberry Mountains. The quarry is an open pit mine that was once sourced for Magnesite, and it remains an active waste pile that sources materials such as basalt, sand, and gravel. Magnesite is a significant iron ore deposit. The area can be characterized by the red magnesite rock outcrops known as the Crosby Deposit and a belt of quartzite that underlays the Crosby Deposit. The Deer Trail group, Stensgar dolomite, and Huckleberry Greenstone can also be found in the area. The magnesite sourced from the quarry did not show enough economic value to continue its mining operation at the time. By analyzing LiDAR imagery of the area, the amount of material removed during the mining operation from Red Marble Quarry may be determined. Possibilities for reclamation or continued mining can also be concluded.
