What started out as a crack in the driveway on Saturday expanded into a 12 foot deep sinkhole Monday morning at the Brett and Kindra Leavitt residence in Afton.
“We watched it get bigger over the weekend and then on Monday morning it fell in,” said Kindra.
The hole continued to expand and crumble throughout the day on Monday.
The Leavitts began work to fill in the sink hole on Tuesday.
“This is the first time I’ve seen this kind of thing happen in Star Valley,” said Brett.
According to the U.S. Geological Survey, sinkholes are common where the rock below the land surface is “limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by groundwater circulating through them.”
According to the USGS, as rock dissolves, “spaces and caverns develop underground.” The land above the sinkhole “usually stays intact for a while until the underground spaces get too big.”
If there is not “enough support for the land above the spaces then a sudden collapse of the land surface can occur.”
