Presented in partnership with the Franklin Co. Rock & Mineral Club. Geologist Jeri Jones Jeri Jones of Jones Geological Services in Spring Grove, Pa. returns to present another fun, fascinating look into our shared geological history.
Admission is free and all are welcome.
In this year’s program, 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 and be used as an introduction to the geology field trip to York County on May 6.
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. 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. Door prizes and free rock and mineral samples will be a part of the program. Questions welcome.
A geologist for more than 30 years, Jones has conducted extensive research on Pennsylvania mining practices, authored several publications, and narrated a 3-part video series on regional geology known as “TimeWalk.” He has been on the faculties of several regional colleges.
This program is presented in partnership with the Franklin County Rock and Mineral Club, and underwritten in part by Marge Kiersz, Lucinda D. Potter, CPA, and SEK CPAs & Advisors.
Additional support provided by The Institute’s Today’s Horizon Fund contributors: The Nora Roberts Foundation; Marge Kiersz; Alma W. Oyer; and the Carolyn Terry Eddy Family: Carolyn, with daughters Connie Fleagle & Kim Larkin.
