Broad Top is a plateau located in south-central Pennsylvania. It extends into Huntingdon County to the north, Fulton County to the southeast, and Bedford County to the southwest. It is bounded to the west by Saxton Mountain and Terrace Mountain, and to the east by Sideling Hill. In Bedford County, Harbor Mountain forms the southern boundary. Trough Creek Valley lies between the mountains.
The Devonian Old Port Formation is a mapped bedrock unit in Pennsylvania, USA. Details of the type section and of stratigraphic nomenclature for this unit as used by the U.S. Geological Survey are available on-line at the National Geologic Map Database. Current nomenclature usage by U.S. Geological Survey restricts the name Old Port Formation to Pennsylvania, but correlative units are present in adjacent states.
There are 24 named waterfalls in Ricketts Glen State Park in the U.S. state of Pennsylvania along Kitchen Creek as it flows in three steep, narrow valleys, or glens. They range in height from 9 feet (2.7 m) to the 94-foot (29 m) Ganoga Falls. Ricketts Glen State Park is named for R. Bruce Ricketts, a colonel in the American Civil War who owned over 80,000 acres in the area in the late 19th and early 20th centuries, but spared the old-growth forests in the glens from clearcutting. The park, which opened in 1944, is administered by the Bureau of State Parks of the Pennsylvania Department of Conservation and Natural Resources (DCNR). Nearly all of the waterfalls are visible from the Falls Trail, which Ricketts had built from 1889 to 1893 and which the state park rebuilt in the 1940s and late 1990s. The Falls Trail has been called "the most magnificent hike in the state" and one of "the top hikes in the East".

Nescopeck Mountain is a ridge in Columbia County and Luzerne County, in Pennsylvania, in the United States. Its elevation is 1,594 feet (486 m) above sea level. The ridge is a forested ridge, with at least two types of forest and two systems of vernal pools. It is a very long and unbroken ridge with two water gaps: one carved by Catawissa Creek and one carved by Nescopeck Creek. This later gap was exploited as a transportation corridor with the construction of the Lausanne–Nescopeck Turnpike between the respective frontier communities at Lausanne Landing and Nescopeck in 1805 connecting the newly developing Wyoming Valley with Philadelphia and the Delaware River valley; cutting off over 100 miles between Philadelphia and Wilkes-Barre. Today's Route PA 93 derives from this historic pack mule road.
Central Mountain is a mountain in Columbia County, Sullivan County, and Luzerne County, in Pennsylvania, United States. Its elevation is 2,247 feet (685 m) 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 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.
