Schoonmaker Reef, also known as Wauwatosa Reef, Schoonmaker Quarry, Raphu Station or Francey Reef is a 425 million year-old fossilized reef in Wauwatosa, Wisconsin. It was discovered in 1844 by Increase A. Lapham and Fisk Day on the site of a quarry owned by the Schoonmaker family. Geologist James Hall declared its significance in 1862. It was the first ancient reef described in North America, and among the first described in the world. It is located North of W. State St., between N. 66th St. and N. 64th St. extended, in Wauwatosa. It was declared a National Historic Landmark in 1997.
