US Highway 93 traverses the Flathead Indian Reservation, which is located on the west side of the Rocky Mountains in western Montana. Picturesque mountains and mountain valleys, with the broad Flathead Valley to the North and the majestic Mission Mountains to the East, characterize this part of Montana. The area is home to a wide variety of wildlife, including grizzly bear, white-tailed deer, mule deer, pronghorn, elk, painted turtles, bighorn sheep, and a number of fish and bird species. It is also home to the Confederated Salish and Kootenai Tribes of the Flathead Nation (CSKT).
