Dans Mountain is located in Allegany County, Maryland, USA between Georges Creek and the North Branch Potomac River.
 The highest point on Dans Mountain is called Dan's Rock which has an elevation of 2895 ft .
 The mountain rises 2200 ft above the town of LaVale and the summit is the highest point in Allegany County.
 Although there are higher points in Maryland, Dans Mountain has the most impressive escarpment of Maryland's mountains.
 It is essentially continuous with the longer escarpment that continues both north (into Pennsylvania) and south (into West Virginia) known as the Allegheny Front.
New Creek Mountain is a mountain ridge of the Ridge-and-Valley Appalachians in Grant and Mineral counties in the U.S. state of West Virginia.
 The mountain is named for New Creek which rises and flows along its western flanks.
 It is part of the Wills Mountain Anticline, with Knobly Mountain along its eastern flank.
 The Allegheny Front rises steeply to the west of New Creek Mountain.
 Oriskany (Ridgeley) sandstone cliffs ring the entire mountain.
Brush Mountain is a stratigraphic ridge in the Allegheny Mountains of central Pennsylvania, USA, running east of the Allegheny Front and west of Tussey Mountain.
 It lies along the southeast side of Little Juniata River and both sides of the Sinking Run, and is the westernmost ridge in its section of the Ridge-and-valley Appalachians.
 The western ridge line separates the Logan Valley from the Sinking Valley.
The Allegheny Front is the major southeast- or east-facing escarpment in the Allegheny Mountains in southern Pennsylvania, western Maryland, and eastern West Virginia, USA.
 The Allegheny Front forms the boundary between the Ridge-and-Valley Appalachians to its east and the Appalachian Plateau (locally called the Allegheny Plateau) to its west.
 The Front is closely associated with the Appalachian Mountains' Eastern Continental Divide, which in this area divides the waters of the Ohio/Mississippi river system, flowing to the Gulf of Mexico, from rivers flowing into Chesapeake Bay and from there into the Atlantic Ocean.
Schaefer Head is a 2950 ft mountain in the Allegheny Mountains of Pennsylvania.
 It is one of the peaks that make up the Blue Knob massif, an isolated group of mountains that stand apart from the Allegheny Front.
 Schaefer Head is the third highest of these peaks behind Blue Knob 3,146  feet (959 m),and Herman Point 3,034 feet (925 m).
 Schaefer Head is also the highest point in Blair County.
Kittanning Gap, one of the gaps of the Allegheny, is a now a relatively unimportant wooded ravine (water gap) along the ascent (at the foot) of the Allegheny Ridge "(also called the 'Allegheny Front' or 'Allegheny escarpment')" in central Pennsylvania in the United States.
 The gap was one of several optional paths of the Kittanning Path Amerindian trail turned into an emigrant route over the Alleghenies in the day of animal powered technology.
 The option up the gap was likely "the 'better choice' of an ascending route" for ox cart and wagon (such as those made downstream in Conestoga, Pennsylvania) encumbered white settlers pouring west across the Alleghenies escarpment.
The Allegheny Portage Railroad was the first railroad constructed through the Allegheny Mountains in central Pennsylvania, United States; it operated from 1834 to 1854 as the first transportation infrastructure through the gaps of the Allegheny that connected the midwest to the eastern seaboard across the barrier range of the Allegheny Front.
 Authorized as part of the Main Line of Public Works legislation in 1824, it was a series of ten inclines connecting to a branch of the Pennsylvania Canal at either end, approximately 36 mi long overall.
 It had five inclines on either side of the drainage divide running athwart the ridge line from Blair Gap through along the kinked saddle at the summit into Cresson, Pennsylvania.
 The Portage Railroad utilized cleverly designed wheeled barges to ride a narrow-gauge rail track with steam-powered stationary engines lifting the vehicles.
 Except for peak moments of severe storms, it was an all-weather, all-seasons operation.
 Along with the rest of the Main Works, it cut transport time from Philadelphia to the Ohio River from weeks to just 3–5 days.
 The roadbed of the railroad did not incline monotonically upwards, but rose in relatively long, saw-toothed stretches of slightly-sloped flat terrain suitable to animal powered towing, alternating with steep cable railway inclined planes using static steam engine powered windlasses, similar to mechanisms of modern ski lifts.
The Kittanning Run is one of the several streams draining the Allegheny Plateau, each one cutting an abrupt valley, one of the gaps of the Allegheny— one of several climbing valleys used for centuries by the Amerindian native peoples to pass East-to-West through the Allegheny Front escarpment, a barrier ridge separating the flat highlands plateau, the Appalachian Plateau—from the many barrier ridges making up the local Ridge-and-Valley Appalachians in the Central Pennsylvania heartland.
Bald Eagle Mountain – once known locally as Muncy Mountain – is a stratigraphic ridge in the Allegheny Mountains of central Pennsylvania, USA, running east of the Allegheny Front and northwest of Mount Nittany.
 It lies along the southeast side of Bald Eagle Creek, and south of the West Branch Susquehanna River, and is the westernmost ridge in its section of the Ridge-and-valley Appalachians.
 The ridge line separates the West Branch Susquehanna Valley from the Nippenose and White Deer Hole Valleys, and Bald Eagle Valley from Nittany Valley.
Central Mountain is a mountain in Columbia County, Sullivan County, and Luzerne County, in Pennsylvania, United States.
 Its elevation is 2247 ft above sea level.
 The mountain is part of the Allegheny Front.
 Rock formations on the mountain include the Pocono Formation and the Duncannon Member of the Catskill Formation.
 It was historically known as North Mountain, but it was renamed Central Mountain (after the village of Central) in the late 1800s.
 The mountain is one of the most important sites on the Columbia County Natural Areas Inventory and it is inhabited by dozens of trees, shrubs, and herbaceous plants.
 Numerous birds and several amphibians and mammals are also found in the area.
