REMARKS: The hard, weather-resistant Burgoon Sandstone (Mississippian age) caps the rim and ridge top. The view of the adjacent gorge, tributary valleys, and High Plateau topography is excellent.
REMARKS: The largest of Pennsylvania's second-magnitude springs (median flow, 5000 to 20,000 gallons per minute), having a median flow of 18,000 gallons per minute; Pennsylvania has none in the first-magnitude category. The spring originates from fractures in limestones of the Nealmont and Benner Formations (Ordovician age) in a secluded, beautiful hemlock grove.

REMARKS: A small village park has been built adjacent to a picturesque cliff exposure of siltstones and mudstones of the Lock Haven Formation (Late Devonian age) along Muncy Creek. The cliff was once the reported site of Indian paintings showing scenes of their life in these hills; all traces of the paintings have disappeared.
291. Williamsport Scenic Vistas
TOWNSHIP: Armstrong
QUADRANGLE: Montoursville South
LOCATION: A large scenic overlook is adjacent to U. S. Route 15 on Bald Mountain, approximately 4 miles east of the city of Williamsport. Several other vistas are located along Skyline Drive on North White Deer Ridge in Tiadaghton State Forest.
REMARKS: Lookouts provide excellent, highly scenic vistas of the Susquehanna River valley, the Allegheny Front, and the Allegheny High Plateau. Highly resistant quartzite (Tuscarora Formation, Silurian age) underlies and accounts for the high elevations of North White Deer Ridge and the northern slope of Bald Eagle Mountain.
