About this map

Middle Phillips Creek and its various tributaries define this section of the eastern Montana rangelands, where the hydrology of the Missouri River watershed begins to take shape. The terrain is a network of coulees and ephemeral drainage systems, including North Phillips Creek and the headwaters of Little Dry Creek. These watercourses carve through the landscape of the Northern Great Plains, revealing a topographical complexity that is often masked by the wide-open horizons.

Infrastructure is sparse in this portion of Garfield County, dominated by the path of Mt-59 as it cuts diagonally across the northeastern quadrant. The map detail reflects the vast, open-range character of the region, where land is measured by the Public Land Survey System grids of t16n r40e and t15n r40e. At the southwestern corner, Knudson Coulee provides a named landmark within this high-plains geography, illustrating the localized names used by ranchers and early settlers to navigate the breaks and draws.
