Boulders have driven the destiny of the Princeton ridge, influencing its ecology and impeding development. The story of these boulders’ genesis and influence will be told during a hike to see remnants of quarries and smallholder farms; magnetic rocks and wildflowers found only along the ridge.

NOTE: Please wear appropriate footwear for outdoor trail walking. Students should meet at the main parking lot for Herrontown Woods, 600 Snowden Lane, across from entrance to Smoyer Park.
