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.[3] 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.[4] It was the first ancient reef described in North America, and among the first described in the world.[2][5] It is located North of W. State St., between N. 66th St. and N. 64th St. extended, in Wauwatosa.[1] It was declared a National Historic Landmark in 1997.[2]
