About this map

Madison Buffalo Jump State Monument stands as the centerpiece of this Gallatin County landscape, marking an ancient and culturally significant Indigenous hunting site on the bluffs above the Madison River. The terrain is defined by a sophisticated network of early water management features, including the Sloan Ditch, Crowley Ditch, and the Lowline Canal, which snake across the valley floor to support agricultural ranching. The hydrology of the region is further detailed by Rey Creek and Spring Creek, showing how these natural watercourses intersect with man-made improvements like the Warm Springs Canal and Darlington Ditch. This 1980s-era survey captures the area's transition into a preserved historical site while maintaining its character as a working landscape, evidenced by several Gravel Pits and various pipelines that traverse the rugged contours of the Madison Plateau foothills.
