The Young granite quarry was opened in 1886 by Youngs Sons & Company. It was located 1 1/4 miles southeast of Milford village, three-fourths mile southwest of East Milford.

The granite was "dark-blue New Westerly," a quartz monzonite of general dark-gray shade (neither bluish, greenish, nor pinkish, but of smoke
color) with very fine black spangles.
