Some coal from this mine has been burned by ranchmen in the valley of No Wood Creek and plans have been made for its further development. The most important mine in the area south of Tensleep Butte is in the badlands at the head of the north fork of Bud Kimball Draw, in sec. 33, T. 46 N., R. 89 W. More coal has been taken from this mine than from any other in the southeastern part of the Bighorn Basin. A section of the bed at the mine is shown by No. 4 on the map. The mine consists of an irregularly widened entry about 75 feet deep. Owing to its mode of weathering, the coal is classed as subbituminous. It has a pitchy luster, medium hardness, and subcubical jointing or cleavage. It contains small nodules of amber-colored resin and thin bands of mineral charcoal. It is probably a noncoking coal and does not stock well. The chemical properties of the coal are shown by analysis 6709, on page 183. The coal is in the Fort Union formation, and, like most of the beds in the field, is lenticular. One-fourth of a mile to the northeast the bed contains only 6 inches of coal, and an equal distance along the strike to the southeast an exposure shows an 8-inch bed included in carbonaceous shale. Although there is sufficient coal in the bed to furnish considerable fuel for local consumption, development has been prevented by the distance to settlements and the difficulty of maintaining wagon roads for transportation. About 3 miles south of the mine on Bud Kimball Draw there is an exposure of a coal bed at the base of a small isolated hill northwest of North Butte. The body of coal at this place is about 1 acre in extent and ...
