Abstract First order drainage basin parameters (area, basin length, basin relief, percent slope, drainage density, and ruggedness number) were examined in nineteen fourth order basins within the eastern Powder River Basin. The fourth order drainage networks were selected from six geomorphic regions within three major river systems, crossing two prominent geologic formations. Parameters of basins located on the Fort Union formation are characteristic of a more rugged topography than those basins measured on the Wasatch formation. The mean values of basin parameters (for the two formations) are significantly different. The structural geology which dictates the general form of the basin may be responsible for these differences. Furthermore, individual T-tests were made in order to compare variation across the geologic contact between river basins. Basin characteristics varied significantly from what might be expected on the Little Powder River and the Cheyenne River. On the Belle Fourche drainage system, results were found to be consistent with what might be expected based on the hypothesis.
