THOMPSON2 Associate Professor of Range Ecology and Range Research Assistant, Animal Science Department, West River Agricultural Research and Extension Center of South Dakota State University, 801 San Francisco Street, Rapid City, SD 57701 INTRODUCTION SOUTH Dakota is located in the geographical center of the North American continent, equidistant from the Atlantic and Pacific Oceans, and midway between the North Pole and the equa­ tor (United States Dept. Interior 1967). The Black Hills are situated along the state's western border (Fig. 1) lying principally within parallels 43 and 45 degrees north latitude and meridians, 103 and 104 degrees, 30 minutes, west longitude, largely in South Dakota, partly in Wyoming (Johnson 1949). Total area is about 5,150 mi2, including the Bear Lodge Mountains in northeastern Wyoming (Orr 1959). After leading a scientific party through the Black Hills in the summer of 1875, Colonel R. I. Dodge (1876) concluded: The Black Hills country is a true oasis in a wide and dreary desert.

  • TIES, MONTANA. by CF BOWEN. Previo
    ANTICLINES IN A PART OF THE MUSSELSHELL VALLEY, MUSSELSHELL, MEAGHER, AND SWEETGRASS COUN­ TIES, MONTANA. By C. F. BOWEN. INTRODUCTION. Previous investigations had shown that the Musselshell Valley, Mont, is an area in which the rocks have undergone considerable folding. On the basis of this information work was begun in June, 1916, to determine the nature and extent of the folds and to make examination as to the possible occurrence of accumulations of oil and gas in them. The work has demonstrated the existence within the area studied of several well-developed anticlines and domes, which seem to offer structurally favorable places for the accumulation of oil and gas. The demonstration of the presence or absence of commercial accumulations of these fluids in the folds has been less conclusive, owing largely to the undeveloped condition of the area. No direct surface indications of oil were observed, but hydrogen sulphide gas escapes from several water seeps in one part of the area. It is also reported that gas was encountered in several wells dug for water. None of these reports could be verified. At the time of the examination drilling operations within the area were confined to two wells. One of these wells, on the Big Elk dome, had reached the Kootenai formation; the other, in the Woman's Pocket anticline, was probably somewhat more than halfway through the Colorado shale. In neither place had oil been discovered. Two other wells, one about 15 miles east of the area and the other about 12 miles south of the central portion of it, had previously been drilled through the Colo­ rado shale without any discovery of oil.
