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 lead 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.
