The fossils at DAR state park are exposed in about 10 meters of dirty gray limestone exposed as a series of shelves about 20cm high with thin shale interbeds. The rocks are Middle Ordovician -- probably Trenton age rocks of the Glens Falls formation. Collecting is surely forbidden there. The ledges are best explored in the Autumn when the lake level is 160cm (5ft) below its Spring peak.
