2020 Map of Kelly Hills

About this map

The Yellowstone River cuts through the southern portion of this landscape, serving as the primary geographic anchor for the surrounding valley and its agricultural infrastructure. In this 2020 record of Sweet Grass and Park counties, the complex water management systems of the era are clearly visible, including the Hunters Hot Springs Canal and the Prather Mayborn Westfall Ditch. These irrigation features support the ranching and farming operations that define the river basin below the prominent Kelly Hills. North of the river, the terrain is defined by a series of drainages such as W Fork Duck Cr and E Fork Duck Cr, while the historic transportation corridor is traced by the N Yellowstone Trail Rd and Convict Grade Rd. The map illustrates the transition from the high, dissected hills down to the fertile, managed riparian zone along the Yellowstone.
