Penns Valley and the surrounding ridges of the Ridge-and-Valley province dominate this 2016 survey, where the border between Centre County and Mifflin County follows the high ground of Long Mountain. The landscape is a study in agricultural and geological patterns, with long-established settlements like Spring Mills, Farmers Mills, and Potters Mills situated near the water sources of Penns Creek and Sinking Creek. These creeks often disappear into the limestone geology characteristic of the region, evidenced by labels like Rising Spring.
