Observing Glacial Erratics Along the Ronkonkoma Moraine

Observing Glacial Erratics Along the Ronkonkoma Moraine: This program is for adults and teens.

Walk Leader: Frank Quevedo, SOFO Executive Director

The geologic event that most greatly affected the land surface of Long Island was the advance of a massive continental glacier into this region during the Wisconsin stage of the Pleistocene Epoch. The Ronkonkoma and the later Harbor Hill are two sub-stages, or positions, of this ice sheet which occurred on Long Island. https://www.garviespointmuseum.com/

This walk with Frank will give you an up-close view of glacial erratics – often the size of boulders – deposited as the glacier melted and retreated
