2024 Map of Horse Lake

About this map

The high plains of Glacier County are defined here by the significant drainage divide of Milk River Ridge, where water flows toward disparate basins. To the north, the South Fork Milk River and Toad Creek feed into Horse Lake and Toad Lake, while the southern slopes are carved by the complex headwaters of the Greasewood system. This hydrological network includes the North Fork Greasewood Creek, Middle Fork Greasewood Creek, and South Fork Greasewood Creek. Evidence of regional water management is visible in the Cut Bank Greasewood Canal located in the southeast. Movement across this landscape is marked by historic routes such as the Arnoux Trl and Duck Lake Rd, reflecting a long-standing pattern of ranching and transit through this portion of Montana.
