The Friends of Panthertown Valley will offer a presentation, titled “Whence These Mountains? The Geology That Makes Cashiers and Panthertown Special,” from 5:30-7:30 p.m. Tuesday, July 18, at the Albert Carlton-Cashiers Community Library.

Refreshments will be served, and admission is free.

This presentation is for those who want to know the history of these mountains or learn about the big rock walls down Lonesome Valley and Panthertown Valley, or why Cashiers’ valley is so much higher than the valleys in Sylva or Franklin, and why roads get so steep and curvy in all directions.

Bill Jacobs got an itch to understand these things, and for the past several years he has been taking courses, reading the literature and doing field trips to get answers. He is not a geologist, but he has become a pretty serious geology buff. He has found a story that he enjoys sharing with his Cashiers neighbors and friends. He will do this in a lecture full of illustrations, photos and rock samples, and with the bare minimum of technical jargon.

Attendees can arrive early for a chance to win one of several Panthertown-related door prizes. There also will be a drawing for the raffle of a YETI cooler.
