2017 Map of Johnson Reservoir NW

About this map

The Big Sheep Mountains dominate this high-plains landscape in Dawson County, where the terrain is deeply dissected by a network of seasonal drainages. Waterways such as Bluff Cr, Brush Cr, and the Middle Fork Deer Cr carve through the land, illustrating the complex erosional patterns characteristic of this part of Montana. The map provides a look at the rural infrastructure and land divisions within t20n r51e, t20n r52e, t19n r51e, and t19n r52e. Local movement across these ridges and valleys is facilitated by a grid of rural routes including Fas 470, Rd 452, and the notably named Abac 13-W. This survey is particularly useful for understanding the exact positioning of creek beds and topographic elevations in an area where the natural drainage system is the primary landmark.
