About this map

Pea Ridge stands as the central topographic feature in this arid stretch of Phillips County, where the landscape is defined by an intricate network of erosional drainages and localized water management. The drainage pattern of Fourchette Cr and its tributaries, such as the N Fork Fourchette Cr and S Fork Fourchette Cr, dominates the terrain, creating numerous coulees that carve through the high plains.

Strategic water catchment is evident through several named basins, including Siwash Reservoir, Shale Reservoir, and the uniquely named Fish Fossil Reservoir. These features, along with names like Horse Pasture Coulee and Hardpan Coulee, reflect the ranching heritage and geological character of this remote Montana region. Only a single named thoroughfare, Midale Rd, traverses the northern portion of the quadrangle, emphasizing the sparsely populated, open-range nature of the country during this era.
