Newburg and the small settlement of McKinney anchor this landscape where the ridges of the Appalachian Mountains meet the fertile valleys of central Pennsylvania. The geography is defined by parallel heights, including Sherman Mountain and Blue Mountain, which frame narrow corridors like Gunter Valley. These natural barriers have long dictated the path of travel and settlement, with roads following the contours of the land and water gaps like First Narrows and Second Narrows.
