Geologic activity over the last 417 million years has removed or covered up most Silurian rocks. Well-preserved fossils from Silurian reefs can be found in the Great Lake States of Minnesota, Wisconsin, Michigan, and Illinois. Silurian rocks can also be found exposed in the Appalachian Mountains, New York, and New England, as well as below the surface in many other states.
