Saline, Eddy, and Varmint traces met at Big Spring (Princeton) and developed into today's roads. First forged by buffalo, later used by Indians and pioneers. A fork of Saline crossed Ohio River at Cave-in-Rock; another at Golconda, Ill. Eddy Trace also known as Palmyra-Princeton Trail. Varmint Trace ran from Princeton to Cumberland River.
