About this map

Iliad centers this agricultural and grazing landscape in Chouteau County, where the high plains are dissected by numerous dry washes and drainage systems. The settlement is positioned along Judith Landing Rd, a primary transit corridor that cuts diagonally across the township lines. To the south, the terrain rises significantly at the Eightmile Bench, a prominent plateau overlooking the surrounding coulees.

Water management and erosion patterns define the topography, evidenced by features such as Sandstone Coulee, Clutchbaugh Coulee, and the seasonal flow of Chip Cr.. The road network, including Iliad Loop and Eight Mile Bench Rd, follows the natural contours of the land, connecting isolated ranching operations. This 2017 survey documents the enduring spatial organization of Montana's central plains, where naming conventions like Sage Coulee and Clinard Coulee reflect the local geography and historical land use.
