About this map

St. Marie sits at the northern edge of this high plains landscape, characterized by the intricate drainage systems of Uhlan Coulee and Enright Coulee. These geographical depressions, along with Johnson Coulee to the east, define the local topography as they feed into larger water systems. The map details the hydrology of the region through reliable water sources like Hermans Spring and Ericson Spring, which provided essential resources for early ranching and homesteading in this part of Valley County.

Lower elevations are dominated by Porcupine Valley, where Porcupine Cr meanders through the terrain. A network of rural routes, including Spring Coulee Rd and Nyquist Rd, connects the scattered landmarks and agricultural sections. The survey preserves the precise layout of the t30n r41e and surrounding township boundaries, offering a clear record of land division and the seasonal waterways like E Fork Cherry Cr and Sargent Cr that have shaped local movement and settlement patterns for generations.
