2017 Map of Lookout

About this map

St. Marie and the small community at Porcupine Valley anchor this portion of Valley County, where the plains of northeast Montana transition through a network of drainage systems. The landscape is defined by the winding course of Porcupine Cr and the seasonal flows of Dry Fork Cr, which together shape the local topography. This 2017 survey shows a region where water management is central to the land's utility, evidenced by the Middle Reservoir and secluded water sources like Olson Springs and Potter Spring. To the east, the terrain rises into the Calderwood Hills and toward the high point at Lookout, while lower elevations are marked by features such as Hay Coulee. This map provides a clear view of the ranching and agricultural grid system that persists into the 21st century.
