Visit two road-cuts on Transmountain Road which contain the oldest rocks in the El Paso region, and some of the oldest rocks in Texas. Thanks to the construction of Transmountain Road, the belly of a supervolcano has been exposed, and you will be right inside of it. Your guide will explain the history and geology of this amazing part of the Franklin Mountains. There is very little hiking, but sturdy shoes, water, and a hat are required. Meet at the El Paso Museum of Archaeology parking lot at 9 AM and carpool from there. (MAP)

CAUTION: You will be near the side of the road, and all visitors must remain OFF the blacktop for their own safety. There will be an unofficial “Bright Clothing Contest” so bring your favorite roadside outfit to show off! For more information contact Dr. Kappus at Southwest University:
