Mifflin County, Pennsylvania
Mifflin County lies in central Pennsylvania's ridge-and-valley country, where the Juniata River collects Kishacoquillas Creek at Lewistown and ridges enclose Big Valley, farmed by Amish and Mennonite families. Manufacturing in the Mifflin County Industrial Park anchors employment, and with buildable land confined to narrow valley floors along the Juniata, new proposals including a Granville Township data center compete directly with floodplain and farmland.
