Visit historic Sunflower Mine (a.k.a. National Mine). When you reach the mill, you’ll see a giant steel pipe that tumbled a reddish-brown ore called cinnabar. The resulting fine particles were burned in vertical furnaces with coke to produce mercury gas. The gas liquified after being cooled in giant U-shape tubes. Most of this equipment is still standing inside a large dilapidated wooden building. Large mines are scattered on hillsides around the mill. Never enter a mine regardless of how safe it may appear.
