About this map

The Kelly Hills dominate the central landscape of this Montana survey, providing a rugged backdrop to the drainage basins of the Yellowstone River. To the north and west, the terrain is defined by the winding paths of E Fork Duck Cr and W Fork Duck Cr, which carve through the high ground before meeting the main branch of Duck Creek. A distinct boundary line separates Sweet Grass Co and Park Co, cutting across the southern portion of the map where the elevation drops toward the river valley.

Transportation corridors follow the natural topography, with N Yellowstone Trail Rd and the Frontage Rd paralleling the river's course. These routes, including the curiously named Convict Grade Rd, reflect the historical movement of goods and people along this major waterway. Small tributaries like Hunters Cr and Jarrett Cr feed into the river from the south, marking a transition into more level valley land compared to the broken hills to the north.
