Cooper, Nathan, Gristmill

The Nathan Cooper Gristmill is a historic gristmill on the Black River in Chester, Morris County, New Jersey, United States. From the 1760s until 1788 Isaiah Younglove milled flour on the site. Several other millers owned the mill, until Nathan Cooper constructed the present mill in 1826. The mill is currently kept in operating condition, with the large water wheel turning shafts and gears that turn 2,000-pound mill stones. The Morris County Parks Commission owns and operates the mill. The Friends of Cooper Gristmill, non-profit organization, contributes money and expertise to run the mill.
