The Bureau of Land Management’s Prospect Hill Interpretive Area lies in a turnout off Natrona County Road 319 about eight miles southwest of Rock Avenue and 1.4 miles southwest of Willow Spring. To find the turnout, drive southwest a mile from the Willow Springs area. In 0.8 mile, about halfway up the hill is a pullout with a good view of the swales cutting the slope. Near the top of the ridge, 1.4 miles from Willow Springs, watch for a BLM directional sign and a gravel road on the right. Turn onto the road, which leads back about one quarter mile to the BLM interpretive site.
