Goat Hill

Goat Hill, also called Bellvue Dome, is a dome near Bellvue. The dome has a gradual slope on its east side, but its west side is an almost-vertical cliff that hangs over the Cache la Poudre River that passes directly below. The mountain itself is on property owned by the Bureau of Land Management, but it's surrounded by private land, so access is difficult or impossible without permission from the adjacent property owners. Goat Hill is prominently seen by motorists driving south on Highway 287.
