Apple River Canyon State Park

(Illinois)

Apple River Canyon State Park is an Illinois state park on 297 acres (120 ha) in Jo Daviess County, Illinois, United States. The park was begun with land purchased by the state in 1932, as a result of a prolonged campaign led by botanist Herman Silas Pepoon; with additional acquisitions since, 1,907 acres (772 ha) of land have been preserved to protect much of an 8+1⁄2-mile (13.7 km) long canyon on the Apple River.
