Cove Mountain is a pair of mountain ridge lines in Perry County, south central Pennsylvania, in the United States. A part of the Ridge-and-Valley region of the Appalachian Mountains, Cove Mountain is a syncline that is located near the borough of Duncannon, and is approximately 15miles north of the state capital of Harrisburg.[1] A 353acres portion of the mountain was purchased by the Pennsylvania chapter of the Nature Conservancy in 2017, and is operated as a nature preserve that is open to the public.[2]
