The 2015 GSW Spring field trip is scheduled for Saturday, May 2, 2015 and will be a cross section through karst areas of the Mid-Atlantic Piedmont to the Great Valley. This trip will start by looking at the intersection between karst and society by examining sinkhole development in the Wakefield Marble near New Market, Maryland, and within the Cambro-Ordovician limestones of the Frederick Valley at Frederick, Maryland. Next, a commercial cave tour of Crystal Grottoes in Boonsboro, Maryland (if possible). Spring-fed tufa, travertine, and marl soil development will be seen at Fairplay, Maryland. Caves and solutional features will be seen along the bluffs of the Potomac River within the C&O Canal National Park at McMahon’s Mill. Finally, karst topography will be discussed in relation to the epic Civil War battle fought at Antietam National Battlefield.
Trip participants should congregate at the McDonald’s located at the New Market exit 62 off of I-70 in Maryland. The trip will begin at 9 am and end at Antietam National Battlefield at dusk. Parking is not an issue, so multiple vehicles are permitted.
