Over the Independence Day weekend, I took my family to the Bonne Terre Mine, about 50 miles south of St. Louis on Highway 67. It was once one of the world’s largest active lead mines, and the area around Bonne Terre is still known as the Lead Belt. Mining is still the major industry in southeast Missouri, and the area is dotted with big piles of mining waste, which the locals refer to as “chat.”
Mining in the area started way back in 1720 by French settlers; Bonne Terre Mine opened in 1860. It closed in 1962.
