Stark's Knob, Geological formation near Schuylerville, United States.
Stark's Knob is a rock formation near Schuylerville made of basaltic pillow lava that formed from underwater volcanic activity about 450 million years ago. The layered rock shows the geological story of an ancient shallow sea and helps scientists understand how volcanic rocks develop in marine settings.
The site got its name from General John Stark, who stationed his troops between this rock and the Hudson River in 1777 to block British forces from escaping. This strategic position during the American Revolution made the location historically important to the region.
The site serves as an educational center where students and researchers examine the geological processes of the Ordovician period through field studies.
The rock formation is easily accessible near Hudson Crossing Park, where visitors can walk around and view it up close. Information about the site and its geological importance can be found through the New York State Museum.
The rock originally came from the Connecticut River Valley and was pushed westward and tilted by tectonic forces over millions of years. This long-distance journey below the earth's surface shows how powerful geological processes shaped the landscape.
