The photographer who goes under the pseudonym Seph Lawless is back at it again.
This time he's toured Picher, Oklahoma — the most toxic city in America.
What was once a vibrant mining city has been turned into a toxic ghost town through improper care and disposal of the 14,000 abandoned mine shafts in the region.
What is left of the town is documented in Lawless' new photo book, "The Prelude: The Deadliest City in America."

Even getting into Picher, Oklahoma, is not easy. Roadblocks have been erected on roads leading to the town since it was evacuated in 2006.
The problems in Picher date all the way back to the early half of the 20th century.
The land was found to be rich in lead and zinc ore, and between 1917 and 1947, $20 billion worth of the toxic material was mined out of the Picher region.
