On Monday I asked about what kind of rocks these large Celery Farm rocks are, how'd they get here, and where are these

They are called glacial erratics, brought here by glaciers during the Wisconsin Ice Age. Congrats to Ginny , Rick Radis and Irene Auleta for correctly answering.

One is near Carlos' Bench by Phair's Pond (left), and the other is located across the Allendale Brook not too far from the bench dedicated in memory of Jeanette Limatola (right).
