1983 Map of Spring Valley East

USGS Topo · Published 1983

About this map

Little Porcupine Creek and its various forks define this portion of Valley County, where the high plains transition into a complex drainage system. This 1983 provisional survey highlights the intricate land divisions across townships T32N, T31N, and T30N, reflecting a landscape dominated by ranching and open range. Remote infrastructure is sparse, yet the presence of an Airstrip in the western reaches suggests the necessity of aerial access in this expansive Montana terrain. The confluence of the West Fork Spring Valley Fork and East Fork Spring Valley Fork provides a clear view of the natural watercourses that have historically shaped land use and navigation in the Fort Peck Indian Reservation area.
