Hacklebarney State Park in Chester, New Jersey, is a 978-acre park along the Black River, known for hiking trails that wind past boulders, waterfalls, cascades, and autumn woodland scenery. Its landscape was formed by the river and its tributaries, Trout and Rinehart brooks, and includes mineral-rich deposits and a diverse natural community of birds, wildlife, and endangered plants. The land also reflects a long human history, from Native use by peoples including the Lenni Lenape to agriculture and more than a century of iron mining. Donations by Adolphe E. Borie and Sarah Borie established the park, and Civilian Conservation Corps workers later shaped many of its trails and facilities.
