Giant Sinkhole Opens Up In South Dakota, People Go Inside It To Investigate And The Pics Go Viral


About a dozen houses in Black Hawk, South Dakota, were evacuated after a sinkhole opened under the Hideaway Hills development. The ground started to give way on the 27th of April and while it has left a lot of uncertainty for the locals, the situation has led to a unique discovery. The residential homes were built over an abandoned gypsum mine.

 

The authorities are already trying to figure out how this could’ve happened but in the meantime, explorers of a local caving group called Paha Sapa Grotto decided to take a look inside.

 

 

The Paha Sapa Grotto is a subchapter of the National Speleological Society and is a world leader in caving science, exploration, and conservation. “When we heard about the sinkhole, we knew it was on a geological unit that could potentially have caves in it,” Nick Anderson, a member of Paha Sapa Grotto, told Boredmojo “We also knew that county emergency management wouldn’t have much experience in this area so we offered to help to determine the scope of the problem.”
