Take your survival gear. Looks like a great place to me to hang out for 3 or more days.
"There are precious few places in the plains where a light is not visible on the horizon at night. Bitter Creek is one of those places. Stretching north of Glasgow to southern Saskatchewan, it is a land of grass; the largest remaining on the U.S.—Canadian border. In Montana, its core is the Bitter Creek Wilderness Study Area (WSA)—59,000 acres of glaciated plains and badlands where you could hike all day without seeing another soul or hearing the sound of an engine."
