What did Montclair and the surrounding area look like during the height of the Ice Age, 20,000 years ago? Imagine a thousand feet of blue ice covering First Mountain, chilly lakes of meltwater, a frigid gale roaring off a glacier, and mastodon and reindeer roaming the tundra. A presentation by Greg Pope, a Montclair State University geology professor, will explore this strange prehistoric Montclair landscape with current landscape scenery, maps, and analogous locations. Nearby, the Great Falls of Paterson was a spillway for Glacial Lake Passaic, and the Meadowlands were Glacial Lake Hackensack. In Montclair, signs of the Ice Age are still around us, from Anderson Park’s boulders to the cliffs of Mills Reservation.
