The study of the depositional history of the Edgecliff reefs is complete. Major results include: the identification of the Edgecliff and its reefs as the product of carbonate deposition in a temperate water environment, modes of reef growth, description of the nature of pinnacle reefs, and the basinal dynamics and distribution of pinnacle reefs. A trend was found of increasing number and size of stromatoporoids westwards from the vicinity of Albany, NY (where they are rare and small) to Hagarsville, Ontario, Canada (where they are common and large) due to the assumed solar warming of coastal currents flowing from east to west supports this hypothesis. Further evidence of this warming includes the first appearance of algae (Rothpletzella) in the vicinity of the LeRoy bioherm, LeRoy, NY. Carbon and oxygen isotopic analyses of brachiopods from the Edgecliff further support a cool water model for reef deposition.
