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.
