Petrified Sea Gardens, also known as Ritchie Park, is a National Historic Landmark near Saratoga Springs, New York. It preserves an area of ancient stromatolites in a Cambrian rock layer. Stromatolites "were first recognized, discovered, and interpreted in North America" here, on property owned by Robert F. Ritchie, a stonemason and amateur geologist, who detected them in 1922 and opened a park to show them to the public in 1924.
Stromatolites, which are marine algae growths, were unknown, and it was a puzzle whether these fossils were organic or inorganic products. James Hall (1811–1898), the first State Paleontologist of New York, identified them as being organic and placed stromatolites in a new genus.
The site was open as an educational site operated by a non-profit, the Friends of Petrified Sea Gardens until 2006. It is currently closed to the public. It is located at 42 Petrified Sea Gardens Road, about 0.5 miles (0.80 km) north of N.Y. 29, west of Saratoga Springs, New York.
