2024 Map of Grapevine Dome

About this map

Grapevine Dome rises above a highly dissected landscape in Big Horn County, characterized by a complex network of drainage systems and deep canyons. This modern survey illustrates the rugged southern Montana terrain where the North Fork Grapevine Creek and South Fork Grapevine Creek converge to form Grapevine Creek. The map shows a significant portion of the Bighorn Canyon National Recreation Area, where the waters of Bighorn Lake fill the deep-cut channels of Bighorn Canyon and Black Canyon. The land is defined by prominent topographical features such as Cooper Ridge and the distinctively named Frozen Leg Canyon. These elevations and waterways provide a clear view of the natural borders and geological formations that define this part of the Crow Indian Reservation region as it exists today.
