near parallel ridgelines, where each are made by a succession of peaks of nearly the same height. This Ridge and Valley province is a geological feature that extends from New Jersey into Virginia forming a great barrier of successive valleys. Pisgah Mountain-just across the valley and creek, is located along the southern fringe of northeastern Pennsylvania's Poconos region but is also central to the Southern Anthracite Region of Pennsylvania— known as the site of the Richest Anthracite Seam, in the heart of the Southern Pennsylvania Anthracite Field and the geological province known as the Anthracite Upland section. The ridgeline parallels the escarpment of the Blue Mountain region. The mountain ridge's peaks lie between two nearly parallel ridge lines to the north and south, Nesquehoning Mountain a similar ridge extending north from Mount Pisgah where the two are joined, and to the south across a valley formed by Mauch Chunk Creek, the Mauch Chunk Ridge. The former historic Mauch Chunk & Summit Hill Railway is now a combined bike & hiking trail along both its former paths, and the north trail has an offshoot to the summit of Mount Pisgah that has a view of the surrounding countryside, and particularly of the Lehigh River gap about feet (or more) below. Mauch Chunk Lake Park and Mauch Chunk Reservoir are also located at the base of the mountain in the valley it forms with Mauch Chunk Mountain, a similar ridgeline in the ridge-and-valley Appalachians north of PA-Rt 443. At the Mauch Chunk-Bear Mountain Gap east of Jim Thorpe, the range ends rapidly descending to the Lehigh River Valley below the northeastern summit marked on USGS topological maps as Mt. Pisgah, which is named for the biblical mountain in Jordan from which Moses first saw the promised land (as are many mountains around the world and especially in the United States). During the late 19th century and early 20th-century, this mountain was a favorite summer resort for those from eastern cities, even as far away as New York City for it sported what has been called the world's first roller coaster, the gravity railroad founded in 1827 by the Lehigh Coal & Navigation Company, builders of the Lehigh Canal and the tourist attracting Mauch Chunk & Summit Hill Railway, which formed a loop between South Mauch Chunk (now the south part of Jim Thorpe, PA) and Summit Hill, Pennsylvania, the site of the
