The Agassiz Bedrock Outcrop is a geographic feature of Ellsworth, Maine that is significant in the history of geology. Located at 406 State Street (U.S. Route 1A), it is an outcrop of Ellsworth schist marked with striations created by glacial action between 25,000 and 13,000 years ago. This outcrop was analyzed by Harvard University geologist Louis Agassiz in 1864 and described in his groundbreaking 1867 paper, Glacial Phenomena in Maine. It was listed on the National Register of Historic Places in 2003.
