History of Westchester County, New York, Vol. II

Evidence points out that Horse creek formerly flowed south of Sixty-six mountain and down the valley of the Pumpkin. The wind drift of ages swept over and buried it in the west end of the county, but the flow of much of its water is through the sands and subterranean channels of the Pumpkin valley to this day.

Should the commonwealth evenly sink a mile the entire state would be under water except a small area on the Flowerfield swell.
So far as has been shown, the Mastodon was the first settler in the valley of the Pumpkin; and that was when the surface of that part of the world was many feet below its present level. In the well being put down on the homestead of S. B. Shumway, at a depth of sixtyfour feet, the remains of one of these primitive monsters was encountered. How much of it is there no one knows, but it is certain that we removed a part of the upper jaw containing two back teeth.
