Abstract
The Glen Ullin quadrangle occupies approximately 51 square miles inwestern Morton County, southwestern North Dakota. Glen Ullin, a small agricultural community on the Northern Pacific Railroad, about 52 miles west of Bismarck, is near the center of the quadrangle (fig. 1).
The Glen Ullin quadrangle is one of a group of 14 adjoining 71/2-minute quadrangles (fig. 1) that are being mapped by the U.S. Geological Survey to furnish a basis for classification of lands withdrawn by the Federal Government pending classification for coal and to contribute to the geologic map atlas of the United States. Most of the fieldwork for the Glen Ullin quadrangle was done during the late summers and early falls of 1964 and 1965.
During the summer of 1966 the U.S. Geological Survey conducted a drilling program in the Glen Ullin and nearby quadrangles (Smith, 1970) to gather information on the existence, thickness, and depth of lignite beds in withdrawn Federal lands. Three of the holes drilled are in the Glen Ullin quadrangle.
