Earnscleugh Flat was once flat, now it's stacked 20 meters high with tailings produced from the 'Alexandra'. A massive floating factory that ate away at the land like a giant caterpillar on a leaf. The Earnscleugh Tailings Heritage site is a great place for a walk or a mountain bike ride. Lots of old parts of the dredges are on the side of the trail you can check out. There is a full 2-3 hour trail that goes right over and around the tailings, or a quick 20 minutes up to the look out and back.
