Take a 5 to 6 hour drive-and-stop tour of the highlights of El Paso Geology. “El Paso is an unusual geologic setting with rocks of diverse ages, mountains of diverse origin and form, and a variety of mineral resources nearby. Seas and lakes, deserts and glaciers, volcanoes and igneous intrusions, faulting and folding, erosion and deposition all have left their marks on the geology and landscape of this region.” (William C. Cornell) Meet at overlook at intersection of Rim Road and St. Vrain Street. MAP Contact: Phil Goodell (the founder of Celebration of Our Mountains), philipgoodell@gmail.com.
