The Harris granite quarry was located a half a mile north-northwest of the North Acton railroad station, and operated by the North Acton Quarry Company. It was opened by D.C. Harris in 1885, and in 1910 measured 200 by 100 feet and from 10 to 35 feet deep. The stone was used for buildings, monuments, and curbing. Examples include the James Wetherbee monument in Woodlawn Cemetery, Acton MA, and the Dunlop monument, Sleepy Hollow Cemetery, West Acton, MA.

According to "The Commercial Granites of New England"; The granite was a biotite muscovite quartz monzonite gneiss of light bluish-gray color and of fine gneissic texture, with feldspars under 0.2 inch, exceptionally up to 0.3 inch, and mica up to 0.1 inch. Its constituents, in descending order of abundance, are milk-white soda-lime feldspar (oligodase), some of it much kaolinized, some minutely intergrown with quartz (vermicular structure): in nearly equal amount, clear to translucent bluish potash feldspar (microcline and probably orthoclase); clear colorless quartz, strained, with rutile needles and some cavities; biotite(black mica), some of it chloritized; and muscovite (white mica).

The Acton Monument Company is the modern incarnation of the Harris company, but they no longer use Acton-quarried stone.

Part of the Harris Quarry land, including the flooded pit, is now private property with a home and contemporary art museum.
