Tiadaghton State Forest and Bald Eagle State Forest dominate this landscape in central Pennsylvania, where the ridgelines of the Ridge and Valley province run in parallel southwest-to-northeast bands. The terrain is defined by dramatic elevations including Bald Eagle Mountain, Nittany Mountain, and North White Deer Ridge. Waterways such as White Deer Hole Creek and Spruce Run cut through these ridges, creating natural gaps that dictate the path of human infrastructure.
