"Rhyolite" is a term that archaeologists working in the Middle Atlantic Region use. The rock is actually metarhyolite, meaning that the original rhyolite bedrock had been transformed by heat and pressure long before native Americans were present on the landscape. Using the correct terminology makes a difference since elsewhere in the eastern U.S. are Indian quarries where unaltered rhyolite was exploited.
