Break Neck was a small collection of houses on the east bank of the Hudson, about two miles north of Cold Spring, through which the River-road runs to Fishkill Landing. Many of the best stone-quarries in this town were located there; also the brick-yard of Clark, Esq., and a short distance south of it, the brick-yard belonging to the estate of Daniel Fowler, deceased. These are the only places where brick was manufactured in this town. It takes its name from Break Neck Hill, at the southern base of which it lies. There was a dock, erected by the Harlem High Bridge Company, who rented from Messrs. Howard & Haldane, a few years since, their stone-quarries and the adjacent land, from which a greater part of the stone at this place was shipped.
Breakneck Quarry was known in the 1830s as Blunt's Quarry, then as the Highland Granite Company (owned by Howard and Haldane), then the Harlem High Bridge Company. Storm King granite was quarried from the south face of Breakneck Ridge to supply material for the Old Croton Aqueduct (built 1837-48). A rock mass near the top of the south face of Breakneck—known as Turk's Head, Anthony's Face, and Upper Anthony's Nose—was a noted tourist attraction until 1846, when it was dynamited by Captain Deering Ayers, bringing down 10,000 tons of granite with a single blast.
