Farmer Gary Dalton of Circleville, Utah, Finds Mysterious Crater in His Pond That Baffles Geologists

September 4, 2014

Gary Dalton, a farmer from Circleville, Utah, has found a huge crater in an irrigation pond on his property, and the concentric circles have confounded geologists.

There were several theories about what could have created the holes, the largest of which is about 25 feet in diameter, KLS.com reported:
- A natural spring, pushing up from under the pond after recent rains.
- A pipeline leak.
- Methane gas creeping out from decaying organic material under the pond.
- An earthquake.

Adding more intrigue to the mystery, Dalton told KLS.com that he saw meteor streaking across the sky a few weeks ago. He described the crater as "Martian art."

Bill Lund, lead scientist with the Utah Geological Survey, who investigated the crater, debunked those theories.

Lund told KLS.com that the crater most likely resulted from repeated draining and refilling of the pond. He said the phenomenon is called collapsible soils, where soil collapses under the weight of water, creating what resembles an eruption.

Still, Lund says he has never seen anything like it and was a little tentative. “There are still some unanswered questions here," he said.

After a very wet first half of December hopes were high that the beginning to the end of California’s years-long drought might finally be at hand. However, virtually no rainfall has fallen across the state since December 18th and none is forecast until at least January 18th. Yet again, a month-long mid-winter dry spell has befallen the state.

What the 5th IPCC Assessment Doesn't Include

Melting permafrost has the potential to release an additional 1.5 trillion tons of carbon into the atmosphere, and could increase our global average temperature by 1.5°F in addition to our day-to-day human emissions. However, this effect is not included in the IPCC report issued Friday morning, which means the estimates of how Earth's climate will change are likely on the conservative side.
