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.
"This is how my eye healed itself after I got run over and landed on a stick with my left eye socket. Not sure about you guys, but I am keeping this! Also, I have a slight far sightedness, but for the rest my sight is perfectly normal."
