In Nevada we saw Arrow Canyon, about 50 miles north of Las Vegas, location of the Mississippian-Pennsylvanian Global Strati- graphic Section and Point (GSSP). This dramatic canyon displays strata from the mid-Cambrian through the mid- Permian and has been a center of Paleozoic stratigraphic research for decades. From there we drove south through Death Valley to the Eastern Front of the Sierra Nevada. We camped at the foot of a cinder cone and saw the western edge of the Basin and Range extensional regime. Our trip culminated in a visit to Mono Lake.
