From the 1950s until 1968 visitors to the Black Hills of South Dakota could purchase tickets for a ride in a jeep to Harney Peak. The ride would take visitors up to the CCC built lookout at the top of the peak, the tallest point in the United States east of the Rockies (visitors could also hike or ascend via horseback). You can view various pictures of and from the lookout here. Erosion due to the jeep trail ended the trips by jeep. The area around the peak was also turned into a wilderness area (and one could argue given the road how that might happen, but that’s another a debate for another time), so no vehicles are allowed anymore.
