A massive sinkhole opened up on a football field at Gordon Moore Park in Alton, Illinois, swallowing a light pole, benches and artificial turf.
The hole was caused by subsidence from nearby underground limestone mining and is at least 100 feet wide (30.5 m) and up to 50 feet deep (15 m).
The incident was captured on security video. No one was injured.
Surrounding roads and the park are now closed and the mining company has reported the hole to the Mine Safety Health Administration.
