About this map

The Yellowstone River anchors this landscape in eastern Montana, carving a wide path through the prairie terrain of southern Prairie County. Near the river's bend sits Calypso, a point of interest connected by the legacy of the Milwaukee Rd and the path of W Old Hwy 10. The topography is defined by the sharp rise of Sheridan Butte and the drainage patterns of numerous waterways including Cherry Creek, Sullivan Creek, and Lost Boy Creek.

Navigation along the river is marked by Wolf Rapids, while the surrounding land is etched with features like Conns Coulee and Calypso Spring. The map reveals a transition between the river valley and the higher breaks of the North Fork Lost Boy Creek, illustrating the classic Missouri Plateau character where transport routes traditionally followed the easiest grades of the water and rail corridors.
