Blue Mountain is a ridge that forms the eastern (southeastern) edge of the Appalachian mountain range in the U.S. state of Pennsylvania. It cuts across the eastern half of the state from New Jersey to 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.

[edit] Geography
The ridge of Blue Mountain runs for 150 miles through Pennsylvania, reaching an elevation of 2,270 feet (692 meters) above sea level just 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 Gap on 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.[1]
Blue Mountain marks the boundary between the Great Appalachian Valley and the main Ridge-and-valley Appalachians.
[edit] Water gaps
Four of Pennsylvania's major rivers cut through Blue Mountain.
- The Delaware River, which forms Pennsylvania's eastern border with New Jersey, passes through the ridge just southeast of Stroudsburg.
- The Lehigh River, which feeds the Delaware at Easton, passes through the ridge near Palmerton.
- The Schuylkill River, which feeds the Delaware at Philadelphia, passes through the ridge just north of Hamburg.
- The Susquehanna River, which feeds the Chesapeake Bay, passes through the ridge just north of Harrisburg, Pennsylvania's capital.
[edit] The Pennsylvania Turnpike
The Pennsylvania Turnpike system passes through the Blue Mountain at two points.
- The Blue Mountain Tunnel carries 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.
- The 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.
[edit] Blue Mountain attractions in Pennsylvania
- The Appalachian Trail is concurrent with the top of the ridge from New Jersey to northern Lebanon County.
- Hawk Mountain Sanctuary is located at the very northern edge of Berks County.
- Blue Mountain Ski Area is found on the north face of the ridge in the southeastern corner of Carbon County.
- Delaware Water Gap National Recreation Area reaches across Northampton, Monroe, and Pike Counties and into New Jersey, mostly to the northwest of the ridge.
- Boyd Big Tree Preserve Conservation Area in Dauphin County
[edit] Blue Mountain School District
There is also a school district named after the mountain range. It is located just off Rt. 61 in Schuylkill Haven, PA
