Emery quarry still in operation in 1970 by Mr. Di Rubbo who lived next to the quarry. Property now reclaimed. Mistakenly called "De Rubel" by Hiller (1968). Listed as "Emery Mines" on USGS topographic map.

This was the most important of what has been called the Cortlandt Emery Belt locations. Emery occurrences and prospects were spread across several kilometres of terrain, all were historically ascribed to the city of Peekskill, but Cortlandt was divided into several cities, Cortlandt and Peekskill in 1940.
