Rockwall Ctny Historical Foundation: A Glimpse at the Rock Wall - Rockwall

The Rockwall County Historical Foundation will offer rare access to private land for a presentation about the underground rock formation where it’s been exposed by a small excavation. Experts have speculated on whether the subterranean wall is the work of prehistoric people or simply an unusual geological occurrence. Shuttles will depart the Rockwall County Historical Foundation Museum every half-hour from 1-3 p.m. on May 18. $10. See Texas Highways blog about it.
