Interstate 99 (I-99) is an interstate highway in the United States with two segments: one located in central Pennsylvania and the other in northern Pennsylvania into southern New York along US 15. The southern terminus of the route is near exit 146 of the Pennsylvania Turnpike (I-70/I-76) north of Bedford, where the road continues south as U.S. Route 220 (US 220). The northern terminus of the Pennsylvania segment is at an at-grade intersection with Musser Lane just before reaching I-80 near Bellefonte. The Northern segment is entirely concurrent with US 15, beginning at Interstate 180 in Williamsport northward into New York to an interchange with I-86 in Corning. Within Pennsylvania, I-99 passes through Altoona and State College—the latter home to the Pennsylvania State University—and is entirely concurrent with US 220.

Pennsylvania Route 26 is a 125.5-mile (202.0 km) highway in the south-central area of Pennsylvania. Its northern terminus is at PA 150 northwest of Howard; its southern terminus is at the Maryland state line near Barnes Gap in Union Township. Two major destinations along this route are Raystown Lake near Huntingdon and the Pennsylvania State University at State College.
Mount Nittany is the common name for Nittany Mountain, a prominent geographic feature in Centre County, Pennsylvania. The mount is not a mountain but is part of a ridge that separates Nittany Valley from Penns Valley, with the enclosed Sugar Valley between them. On USGS topographic maps, Nittany Mount is generally too small to be considered a mountain and is shown as the lower ridge line that runs below Big Mountain on the west and Big Kettle Mountain on the east side, coming together to form a single ridge line at the southern terminus. This nomenclature is not always consistently applied to the same geologic formation, and there is a shorter Nittany Mountain ridge shown above the Sugar Valley as well.
Pennsylvania Route 150 is a 41.1-mile-long (66.1 km) highway in Central Pennsylvania. Its southern terminus is at PA 26 in Dale Summit, Pennsylvania near State College, at the location of the Nittany Mall. Its northern terminus is at U.S. Route 220 in Avis.
Pennsylvania Route 64 is a 21.3-mile-long (34.3 km) north–south state route located in central Pennsylvania. At its southern terminus in Spring Township, PA 64 continues north from where Pennsylvania Route 26 turns to join Interstate 99 and U.S. Route 220. The northern terminus is at Pennsylvania Route 150 in Mill Hall. During its run, PA 64 carries the names Nittany Valley Drive and Water Street.

Bald Eagle Valley is a low-lying area in Pennsylvania that drains into Bald Eagle Creek between the Allegheny Front and Bald Eagle Mountain, south of the West Branch Susquehanna River, in the Ridge-and-valley Appalachians. The valley is located southwest of West Branch Susquehanna Valley and includes Williamsport, Nittany Valley, and State College in the central portion of Centre County and southern portion of Clinton County.
Bald Eagle Mountain – once known locally as Muncy Mountain – is a stratigraphic ridge in the Ridge-and-Valley Appalachians of central Pennsylvania, United States, 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.
Nittany Valley is an eroded anticlinal valley located in Centre County, Pennsylvania. It is separated from the Bald Eagle Valley by Bald Eagle Mountain and from Penns Valley by Mount Nittany. The valley is closed to the north by a high plateau that joins these two mountain ridges, but is open to the south at the southern terminus of Mount Nittany. The valley drains to Bald Eagle Creek through water gaps in Bald Eagle Mountain formed by Spring Creek and Fishing Creek, along with smaller streams running through Curtain Gap and Howard Gap. The northwest side of the valley between the Bald Eagle Mountain ridge and the lower Sand Ridge is also known as the Little Nittany Valley.
Penns Valley is an eroded anticlinal valley of the Pennsylvania ridge and valley geologic region of the Appalachian Mountain range. The valley is located in southern Centre County, Pennsylvania. Along with the Nittany Valley to the north and east, it is part of the larger Nittany Anticlinorium. It is bordered by Mount Nittany to the north, the Seven Mountains range to the south, and connects to the larger Nittany Valley to the west. There are two smaller subordinate valleys typically associated with the greater valley: Georges Valley in the south, separated by Egg Hill, and Brush Valley in the north, separated by Brush Mountain.
Tussey Mountain is a stratigraphic ridge in central Pennsylvania, United States, trending east of the Bald Eagle, Brush, Dunning and Evitts Mountain ridges. Its southern foot just crosses the Mason–Dixon line near Flintstone, Maryland, running north 130 km (80 mi) to the Seven Mountains of central Pennsylvania, near Tusseyville, making it one of the longest named ridges in this section of the Ridge-and-valley Appalachians.
Bald Eagle Creek is a 55.2-mile-long (88.8 km) tributary of the West Branch Susquehanna River mostly in Centre County, Pennsylvania, in the United States.

The Ordovician Reedsville Formation is a mapped surficial bedrock unit in Pennsylvania, Maryland, Virginia, West Virginia, and Tennessee, that extends into the subsurface of Ohio. This rock is a slope-former adjacent to the prominent ridge-forming Bald Eagle sandstone unit in the Appalachian Mountains. It is often abbreviated Or on geologic maps.
Waddle is a populated place in Patton Township, Centre County, Pennsylvania, United States. It is part of Happy Valley and the larger Nittany Valley.
