Gary Dalton and his two brothers recently discovered a round hole or crater in the bottom of their irrigation pond on their farmland in Circleville, in Piute County, Utah. The outer ring is a depression filled with algae. An inner circle looks as though something erupted from beneath, forming what looks like a small volcanic crater. From those observations, a leading theory emerged: a geologic condition called collapsible soils. The pond has been drained and refilled more than a dozen times in the last two years.The theory is that the repeated loading of weight on the soil eventually led some of the soil under the pond to collapse, creating a small eruption.
