Crystal Mill IV
The Crystal Mill historically known as the Sheep Mountain Mill, is one of the most beautiful and picturesque areas in Colorado state. It’s located above the Crystal River between the towns of Glenwood Springs and Aspen.
A wooden powerhouse built in 1892 it is said that the mill harnessed the river adjacent to the mill to power the air compressor housed inside. Early engineers had built a dam across the river, which funnelled water down the vertical penstock (the ladder-like structure) onto a horizontal wheel, which drove an axle in the penstock which then powered an air compressor. In turn, the enormous compressor ran drills in the nearby Sheep Mountain and Bear Mountain mines. The drills were used to bore holes in the mine walls for the placement of dynamite. After the dynamite was detonated, the miners removed the whole ore.
