Missouri River Odyssey
A half-dozen mustangs glare down from a butte, hooves stamping and tails swishing along North Dakota's Killdeer Mountain Four Bears Scenic Byway. The wild horses belong completely to this world of striated buttes showing eons of mountain building and erosion; sightseers can't help feeling like intruders. The byway, 64 miles on State-22 east of Watford City, follows the Missouri River Valley through country that is part forest-capped mountains and part arid badlands. Mornings, ghostly mist hangs in canyons lined with hardy grass that shimmers like green velvet.
