Consists of clay slate; roofing slate; clay slate approximating to micaceous sandstone; various kinds of limestone; brecciated limestone; and conglomerate composed of pebbles of limestone. Includes what Professor [E.] Emmons has called black slate; in part, Taconic slate, and roofing slate. Age in doubt. Thickness 2,000 feet. Overlain by Talcose conglomerate; is younger than the Quartz Rock, which has been mistaken for Potsdam sandstone, and the Red Sandrock series. The Georgia slate is fully exposed in town of Georgia [Milton quadrangle], Franklin County, northwestern Vermont, where its most interesting fossils have been found.
