This is the Bear Chip Coulee, Silver Creek, and Norwegian Gulch located along the Yellowstone River in Sweetgrass County, near the Gallatin National Forest, (A Coulee is a deep ravine). This is home to the Greycliff Prairie Dog Town Monument a very small park dedicated to the preservation of these willy little critters.

The Yellowstone River flows through here year-round, passing runoff from the rains and snowpack melt in the mountains to the west. A tributary of the Missouri River, it is approximately 692 miles (1,114 km) long and considered the principal tributary of upper Missouri, draining a wide area stretching from the Rocky Mountains in the vicinity of the Yellowstone National Park all the way across the mountains and high plains of southern Montana and northern Wyoming.
