NEW YORK STATE GEOPARKS—LESTER PARK—Stromatolites—by Ed Landing and Alexander Bartholomew

You can walk on a 490 million year-old tropical sea floor just northwest of Saratoga, New York. Lester Park, an outdoor exhibit, was donated to the Museum in 1914 as a "Scientific Reservation." The fossils you'll see at Lester Park are called stromatolites ("layered rocks"). They were constructed by "blue-green algae" on a shallow sea floor that is now exposed. While they were growing, New York and the eastern US lay south of the equator. The stromatolites at Lester Park were the first described in North America and remain a valuable teaching aid for college and university classes nationwide.
