The Story in Rocks: Geology with Sarah West

Posted by SchuylkillCenter

The Wissahickon’s dramatically beautiful rock formations—huge banded gneiss formed deep underground, garnet-studded schist that grace the foundations of so many homes—tell a great story of continents crashing into each other, mountains rising and falling, and time slowly revealing the Earth’s secrets. Sarah West has been leading popular Wissahickon geology walks and talks for many tears, and she shares the stories found in these rocks. You’ll never walk the Wissahickon trails in the same way again.
