Geology at Crown Point

This spot sits on Beekmantown Group (in part), mapped as dolostone and limestone that formed roughly 485 to 470 million years ago. Carbonate rock like this dissolves and weathers readily, so fresh road cuts, quarries, and creek exposures are typically the most productive ground.
