This park features an impressive mining equipment piece, the Sumpter Valley Gold Dredge. The dredge (basically a ship on dry land) unearthed the valley from 1935 to 1954 in search of gold, digging up an estimated $4 million in the precious metal during its lifetime. Visitors can explore the dredge, participate in ranger-led tours, or hike 1.5 miles (2.41 km) of trails through the wetlands. On weekends, the park offers gold panning demonstrations, where you can try your hand at panning for gold and take home your findings for a small fee.
