2017 Map of Greycliff

About this map

The Yellowstone River cuts a wide path through this Sweet Grass County landscape, creating a fertile valley flanked by intricate drainage systems and named gulches. The settlement of Greycliff serves as a central point of interest, situated near the Greycliff Bridge and where the river meets Sweet Grass Creek. Local history is embedded in the terrain names, specifically along the slopes leading to Old Schoolhouse Gulch and the nearby New Schoolhouse Gulch, which suggest the evolution of rural education in this ranching country. The topography is defined by numerous seasonal waterways like Hangmans Cr and Milligan Cr, while the river's slow-moving sections are marked by the Milliken Sloughs. This survey provides a modern look at the long-established transportation corridors along the river, including Old US Hwy 10 and several family-named ranch roads.
