Alley Pond Park lies on a glacier-formed moraine, a ridge of sand and rock that formed 15,000 years ago at the southern terminus of the last Ice Sheet to cover much of eastern North America. The glacier dropped the boulders that sit on the hillsides of the southern end of the park and left buried chunks of ice that melted and formed the ponds dispersed throughout the valley. Geologists call these “Kettle Ponds.” These ponds support a diverse flora, including some of the best spring ephemerals our city has to offer.
Join NYFA on a walk around the ponds to examine the park’s spring flora!
