The Rich Mountains are made up of over 13276 acres of primarily wilderness and primitive backcountry that is not heavily used. The Rich Mountains are remarkable because many of the peaks and ridges are covered with a deep, black porter's loam, a characteristic these mountains share with the Cohuttas. In the Eastern Blue Ridge, such soils are confined to coves.
Aaron mountain, part of the rich mountain chain, has a rounded dome covered with rich, black soil and a wildflower display in spring. An old timber growth believed to be over 129 years old lies on the south face of Aaron Mountain. At Horse Cove, there is a good boulder field and a northern hardwood forest with some possibly record-sized, second-growth trees, especially silverbell.
