I love to go to Picher Oklahoma. It is truly a land of constant change. So here is a little history about Picher that you might not know.
Picher, Zincville, and Hockerville on supplied more that 50% of all lead and zinc used during WWI. The largest population was in 1926, it was 14,252 people. Because of unrestricted subsurface excavation, most of Picher was in danger of cave-ins. Because of ground water contamination, cave-in risk and health issues the town was bought by the state and federal government. Giant piles of mining tailings known as "Chat" are heaped throughout the city and surrounding area.
