Blue Mountain is a ridge that forms the eastern (southeastern) edge of the
Appalachianmountain range in the U.S. stateof Pennsylvania. It cuts across the eastern half of the state from New Jerseyto Maryland, providing a distinct boundary between a number of Pennsylvania's geographical and cultural regions. To its northwest side are the southern and central mountains and valleys, the "coal region", and the Poconos. To its southeast side are the Cumberland Valley, the "capital region", Pennsylvania Dutch Country, and the Lehigh Valley.
The ridge of Blue Mountain runs for 150 miles through Pennsylvania, reaching an elevation of 2,270 feet (692 meters) above
sea leveljust north of the Pennsylvania Turnpike, near the borough of Newburg. Most of the ridgecrest, however, only reaches between 1,400 and 1,600 feet in elevation. The mountain's width varies from 1 to 3 miles.
The southwestern end of the mountain is at Big Gap, west of Shippensburg. (The mountain ridge continues to the southwest towards Maryland under the name of "Broad Mountain".) The northeastern end of the mountain is at the
Delaware Water Gapon the New Jersey border. Mount Minsi, elevation 1,461 feet (445 m), forms the promontory overlooking the Delaware River. The ridge of Blue Mountain continues northeast into New Jersey as the Kittatinny Mountains. [U.S. Geological Survey 1:24,000-scale and 1:250,000-scale topographic mapseries]
Blue Mountain marks the boundary between the
Great Appalachian Valleyand the main Ridge-and-valley Appalachians.
Four of Pennsylvania's major rivers cut through Blue Mountain in
Delaware River, which forms Pennsylvania's eastern border with New Jersey, passes through the ridge just southeast of Stroudsburg.
Lehigh River, which feeds the Delaware at Easton, passes through the ridge near Palmerton.
Schuylkill River, which feeds the Delaware at Philadelphia, passes through the ridge just north of Hamburg.
Susquehanna River, which feeds the Chesapeake Bay, passes through the ridge just north of Harrisburg, Pennsylvania's capital.
The Pennsylvania Turnpike
system passes through the Blue Mountain at two points.
Blue Mountain Tunnelcarries the Turnpike's east-west mainline (Interstate 76) through the ridge in northern Franklin County. The turnpike also tunnels through a parallel ridge of the same mountain just to the west (with the two tunnel portals only 0.2 miles apart; the name of this western tunnel is Kittatinny Mountain.
Lehigh Tunnel, so named to avoid confusion with the former, carries the Turnpike's north-south Northeast Extension ( Interstate 476) through the ridge between Lehigh and Carbon Counties.Both tunnels (each consisting of two tubes) carry two lanes in each direction of travel.
