Spruce Run CreekABOUT THE UNION FURNACE PRESERVE

This 170-acre wooded preserve bordering Spruce Run Reservoir is named for the colonial ironworks that flourished here from 1742 to 1781. Established by William Allen and Joseph Turner for the production of horseshoes, farm implements, and chimney firebacks, the ironworks could produce 500 to 1,000 tons of iron a year. In order to melt the impurities in the iron at 3,000 degrees, slaves and immigrants cut down an acre of forest each day to fuel the furnace. During the Revolutionary War, the ironworks’ superintendent, Robert Taylor, cast military hardware such as cannonballs and rifle barrels. Allen and Turner were British loyalists and fled the area. When the forests were depleted of fuel, the furnace ceased operation. Taylor resumed operations at another foundry in High Bridge until his death in 1821. This facility, considered the oldest in the country, became known as the Taylor-Wharton Iron & Steel Company in 1912. In 1811, the Union Furnace site was sold to Hugh Exton, who built a three story gristmill called “Union Mill.” The County acquired most of the property in 1980, and purchased additional acreage in 2017. Today, this hilly terrain includes young and mature forest, a stretch of the Spruce Run, and the standing chimney of a slaves’ quarters.

RECREATIONAL OPPORTUNITIES

A single hiking trail runs through Union Furnace. The trailhead is located across from the Spruce Run Parking Area. Part of the trail follows a historic mill race which used to supply water to the nearby Union Mill. Then it climbs up the hill and emerges onto Serpentine Drive. The trail is part of the Highlands Trail which extends 150 miles from Storm King Mountain on the Hudson River in New York south to Riegelsville on the Delaware River in New Jersey. Blazed with teal-colored diamonds, the trail combines established trails, new trails, and road walking, and displays the scenic beauty of the Highlands region.

FISHING The Spruce Run cuts through the property and is seasonally stocked with trout. Fishermen must display a state fishing license.

HUNTING Hunting is permitted to control the deer population. Hunters must obtain a special permit issued by the Division in order to hunt in the park. Visitors between September and February are strongly encouraged to wear blaze orange or confine visits to Sundays. See additional information on the Hunterdon County Park System Controlled Hunting Program.

SPRUCE RUN RECREATION AREA : Spruce Run Recreation Area, which borders Union Furnace, is maintained by New Jersey’s Division of Parks and Forestry and the Division of Fish and Wildlife.
