About this map

The international border between Canada and the United States defines the northern edge of this high plains landscape in Phillips County. This 1984 provisional survey documents a region where water management is central to the land's utility, marked by a series of small, dispersed impoundments including Artie Reservoir, Ethel Reservoir, Lester Reservoir, and Sarm Reservoir. These features, along with Nerve Reservoir, suggest a ranching or agricultural environment reliant on capturing seasonal runoff in an arid climate.

Drainage patterns are clearly articulated by the East Fork Whitewater Creek, which flows through the southern portion of the map, and the distinct geographic depressions of Haukos Coulee and Dunham Coulee. The namesake Pea Lake sits near the western margin, serving as a primary natural landmark in a territory otherwise defined by the grid of the Public Land Survey System and the subtle topography of the northern Montana borderlands.
