1968 Map of Tepee Buttes

About this map

Tepee Buttes anchor the southern portion of this landscape where the high plains meet the state line of North Dakota and South Dakota. The survey, completed in the late 1960s, highlights the dominance of the Bowman-Haley Reservoir as it inundates the valley where the North Fork Grand River meets Alkali Creek. This transition from riverine system to reservoir is a significant land-use shift for Minnehaha and the surrounding rangeland. Local history markers like Grave and Graves are preserved on the topography, alongside small, named water features like Beermug Lake and Crooked Creek. The terrain is punctuated by distinctive rises such as Corey Butte, while a Quarry in the eastern section points toward localized extraction efforts in an otherwise sparsely populated ranching territory.
