BUTTE, MT - JULY 06: Single father and lifelong Butte resident, Darren Drabant, 28, sits for a portrait in front of his Butte home with his four children (L-R) Ayden Drabant, 4, Mattea Drabant, 6, Nevaeh Drabant, 2, and Lakieriana Drabant, 7, on July 6, 2017 in Butte, Montana. Butte is home of the toxic Berkeley Pit. Formerly an open pit copper mine, today the Berkeley Pit is part of the largest Superfund site in the United States. In its heyday, in the 1860s, the Butte area was known as the "Richest Hill on Earth" due to the bonanza in copper and other metals. (Photo by Janie Osborne/Getty Images)
