A farmer named Gary Dalton was draining a farm pond when he found the big hole.
"The sun was just right, so I saw this blasted thing that no one had ever seen," he told KSL.com.
The crater is just over 25 feet wide and around 7 inches deep.
Bill Lund heads the Utah Geological Survey. "We've got several theories. Most of them have gone up in smoke," he said.
Scientists say the depression could have been caused by everything from an earthquake to a meteor.
However, the most likely explanation is a simple one. The pond has been drained and filled several times over the last few years.
It’s believed that caused a phenomenon called collapsible spoil. That occurs when a small eruption of air and water bursts upwards through soft dirt and mud.
Dalton has another name for it. “I guess that's Martian art," he told KSL.
