"In order to replace several mines in the Superior field that are near completion, the Union Pacific Coal Company have opened up the D. O. Clark Mine at Superior, Sweetwater County, Wyoming. They first contemplated opening up the individual seams from the out-croppings. This would have necessitated moving the present camp of Superior several miles west of the present site and building several miles of additional railroad. This plan was abandoned because of the burdensome cost. Then the idea was conceived of driving rock slopes down against the pitch of the various seams. By doing so, they could locate the tipple about two miles from the present site of Superior and it would require only about a mile of additional track. This plan was adopted, and construction was started in the early spring of 1937. Since completion, experts have pronounced this mine one of the model bituminous mines of the nation. Built at a cost of over one million dollars, it is capable of producing 7600 tons of coal per day, when up to capacity"--Introduction, page 1.
