The Salina Beds belong to the Upper Silurian of North America, and are the lower subdivision of the Onondaga group. They consist mainly of red marls with limestone, dolomite, and extensive beds of rock-salt, especially in the state of New York. As a whole, these rocks are unfossiliferous, and seem to have been laid down in shallow waters exposed to desiccation. They extend northwards into Ontario, crossing the Niagra river a little above Niagra Falls. Research Salina Beds
