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.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.

However, it’s important to remember that at this point, Paha Sapa Grotto still thought it might be a cave, so Weaver was pretty excited to make a big discovery. “When Doug from emergency management showed up, I told him that we could safely go in if they could pull the cracked concrete off of the hole. Soon, they had a piece of machinery there and with the sidewalk gone, we felt much safer about going in. Nick, Dave, and I went in, and it was immediately obvious that it was a mine. There were a lot of drill holes and old mining debris. On this first visit, I made a quick sketch map of what we could see (about 500ft of mine) and then took it to show the people on the surface. I think that’s when the severity of the issue really set in with a lot of people. I also told them that I would come back with two teams the following day and bring correct gear to correctly map it,” the caver said.On the assessment trip, I went out there with Nick Anderson and Dave Springhetti. When we got to the site, the roads were buckled and the guy who lived in the house next to the sinkhole, John, nicely told us to park further away because we just didn’t know what was happening yet,” Weaver explained. “After some general looking around, we found a fence that seemed sturdy enough to rig the rope to and I rappelled into the hole. These photos you saw of me on the rope are from that initial rappel. When I got to the bottom, I could see 80ft into a large cavity that was at that point under the street. I stopped going forward because the sidewalk and street were bent down and cracked.”
