Geologists call these intriguing depressions "kettles." They were formed over 18,000 years ago when the gigantic ice-age glaciers that covered this region began to melt.pSalt Pond is unique among the kettles of the outer Cape because it has been captured by the ocean. A tidal channel from Nauset Marsh has breached the opposite side of the kettle, allowing salt water to enter. Water levels rise and fall twice daily with the tides.
"Some of the valleys... are circular, a hundred feet drop without any outlet, as if the Cape had sunk in those places, or it sands had run out."
Henry David Thoreau
