ROCKFORD, IA – A sinkhole in Florida has been making headlines after eating up a resort.
This is just one of the latest examples of this geological phenomenon that we’ve been seeing around the world.
In 2010 there was a sinkhole in Guatemala that swallowed up an entire skyscraper and this last year a small sinkhole opened up on part of a sidewalk in Saint Paul.
Sinkholes can happen in many different areas and on Tuesday, we spoke with Heidi Reams, a Naturalist for Floyd County, to see learn about why this can happen in parts of Iowa.
“Our limestone bedrock is easily worn away by the ground water and dissolves underneath it and we don’t have a thick enough base above it and so during any change in conditions that ground just basically sinks into the void below,” Reams said.
Reams said that in Iowa, sinkholes are mostly likely to happen along the eastern border where there is less soil between the ground surface we walk on and the limestone bedrock below.
“Depending on how thick or how close the ground level we’re walking on that void gets, it can actually sink down into the cave or into that opening,” Reams said.
