Kashong Glen, New York

Welcome to Kashong Glen, a deep ravine south of Geneva, New York, that cuts into rocks about 380 million years old! The ravine was carved by Kashong Creek, as it drops several hundred feet into the north end of Seneca Lake. Rocks exposed in the ravine are part of the Hamilton Group, a thick stack of siliciclastic (which means quartz sand and clay-rich) rocks named for exposures near Hamilton, Madison County, New York. The rocks exposed in this gorge were formed during the middle part of the Devonian Period. Kashong Glen is one of the best places in New York State to study the rocks of the Hamilton Group and fossils from the Middle Devonian.
