2024 Map of Ada Creek

About this map

Big Dry Creek and its network of tributaries define this stretch of Garfield County, Montana, showing a landscape shaped by intermittent watercourses and traditional ranching boundaries. The drainage of Ada Creek flows northward through the center of the sheet, joined by smaller systems like L S Creek and Sonny Coulee. This is a largely uninhabited territory where the topography is revealed through named coulees and draws, such as Spring Draw, which provide critical reference points for land management and navigation. The extensive public land survey system grid, including t18n r40e and t18n r41e, illustrates how the territory was organized for settlement and grazing. From the northern reaches of Frazier Creek to the southern orientation of Spring Creek, the map traces the subtle elevation changes of the high plains, providing a modern baseline for researchers examining environmental shifts and water access in eastern Montana.
