The Devil's Millhopper Geological State Park is a 64-acre Florida State Park located northwest of Gainesville, Florida. This state park's main attraction is a huge, 120 feet-deep and 500 feet wide, bowl-shaped, cover collapse sinkhole nestled in North Florida's sand terrain, pine forests, and lush vegetation.Sinkholes can be just a metre across, or more than 100 m wide and deep. They come in various forms, which can be grouped into about six main types ().Solution and collapse sinkholes are formed in solid rock, with the solution sinkhole forming so slowly (over geological timescales) that it is a landform and not a geohazard, and the caprock …

A sinkhole is a void in the ground caused by a collapse of the Earth’s surface layer.

Heavy localised rainfall or large areas of concreted ground can change the natural water flow.Sinkhole number one was found in January and at the time, Oregon State Parks Park Manager Jason Elkins told KOIN 6 News that it measured about 20 feet wide and 15 feet deep.
