USGS Topo · Published 2020About this map
The Black Calf Reservoir sits at the heart of this Valley County landscape, anchoring a drainage network defined by intermittent prairie streams and seasonal coulees. The map details the hydrological reach of Bluff Cr as it wind south toward the reservoir, joined by the headwaters of E Fork Crow Cr and Crow Cr. These waterways trace the natural contours of the northern Montana plains, where the land is carved by features like Hardpan Coulee.
