PARSIPPANY — A number of volunteers were removing debris scattered throughout Troy Meadows during Earth Day weekend.
Troy Meadows is a remnant of the last glacier, a part of ancient Lake Passaic. A huge mass of ice broke off the glacier and rested here, enclosed in a thick layer of glacial debris. As the ice melted and settled, a depression formed, lined with the sediments deposited by the glacier. At one time the meadows were part of a vast lake of glacial melt water that drained through the Great Falls of Paterson. Gradually, the water level dropped and marsh plants invaded the area.
