The first day in the field we visited the "Great Unconfomity" at Frenchman Mountain, just east of Las Vegas. At this location, Paleozoic strata overlie PreCambrian schist and granite in a special kind of unconfromity know as a nonconformity. This unconfromity is called "Great" because it represents approximately 1.2 billions years (or about 25% of the Earth age).
