Experience enchanting views of banded, colorful cliffs that overlook a vast rolling prairie. The area is divided by deep gullies that have taken thousands of years to form from water and wind erosion. See spires, pinnacles, buttes, scoria enscarpments, table tops and sandstone bridges all carved from soft marine and non-marine sedimentary rock which has been shaped and molded over the eons by water and wind. Grass covered rolling benches exhibit sage, greasewood, yucca, juniper, and an abundance of wildflowers in season. Here you may stumble across petrified logs as you catch occasional sightings of wildlife including raptors and reptiles, pronghorn, whitetail and mule deer, elk, and badgers. More recent historical evidence includes U.S. Army troops graffiti on Sheridan Butte dating back to the 1800s. Activities here include hiking, hunting, fossil and rock collecting, camping and experiencing the spectacular scenery of the badlands.
The WSA is located approximately three miles northwest of Terry along the Big Sky Backcountry Byway (Hwy 253) where you will turn left on a gravel road just north of the Yellowstone River. Two vehicle trails give you access to the area. The first is this gravel road which is the Terry scenic overlook and skirts the northeastern boundary. The second is the Calypso trail which which bisects the area from northwest to southwest. Access this by traveling west on Old Highway ten out of Terry for approximately two miles. Turn right on Milwaukee Road for approximately three miles, then cross a one-lane bridge across the Yellowstone River (also the Lewis and Clark National Historic Trail). About a half mile past the river you will find a kiosk that provides information about the area and is the start of the Calypso Trail. Four wheel drive is recommended. There are no parking areas, but you can park alongside the road anywhere that makes sense. Do not drive off the road.
