Geology Program with Jeri Jones 


WAYNESBORO—Geologist Jeri Jones presents a program on local geology on Thursday, May 4, at 7 p.m. at the Church of the Apostles, 336 Barnett Ave. Admission is free and all are welcome.

Hosted by The Institute in partnership with the Franklin County Rock and Mineral Club, “What’s on the Other Side of the Mountain?” combines fun with education and continues The Institute’s popular Geology Rocks! annual geology series.

Jones will discuss the rocks, topography and mineral resources east of South Mountain. The PowerPoint program will cover the geology of Adams and York counties.

“The rocks east of South Mountain are both older and younger than those in the Waynesboro area and span 300 million years in geologic time,” Jones said. “The oldest complex marine animal—the trilobite—and the most famous fossil animal class—dinosaurs—are found only a few miles apart.” 

The presentation will highlight the several continental collisions, a rifting continent and widespread ocean. Questions are welcome and samples of minerals and fossils will be available.

The program is a good introduction to a geology field trip to York County on May 6. For more information on the program or the field trip, visit
