Mount Nittany is the well-known ridge above Penn State University and part of Nittany Mountain, which helps define the valleys of central Pennsylvania. Its name is commonly linked to the Algonquian Nit-A-Nee, interpreted as either “single mountain” or “barrier against the wind,” and it also appears in Penn State folklore. Geologically, it belongs to the Appalachian Ridge and Valley province, where resistant sandstone has left the ridge standing above surrounding valleys. Its modern significance also rests on preservation: after a threatened sale in 1945, Penn State alumni helped protect the land, and later conservation efforts expanded the preserved acreage, strengthening its role as a regional symbol.
