Many area posters on Facebook Sunday night reported an extremely large explosion noise coming from the Moline area near the railroad. The Leighton Township Fire Department Monday issued a statement to explain what occcurred: “Just an update. Yes, there was a big boom tonight in the Moline area. It is only a large bonfire of tree roots, stumps, and pallets. Gasoline is the suspect that was used to start it and cause the boom. Yes, not the best ignition source. There is a burn permit for it and nothing illegal burning. There is a water source and a dozer to put it out if needed.”
