Just below Hideaway Hills, Blackhawk Town is an intricate mining system that residents of this town don't know about!
40 households living in Hideaway Hills in Blackhawk town ( South Dakota, USA) have just been evacuated after a sudden death pit appeared on a street of this residential area, according to Bored Panda. In addition to causing significant loss of life and property, the death pit has revealed an interesting and surprising discovery: Located right below the Hideaway Hills neighborhood is a brittle mine system. But residents of this town are not aware!
The death pit that appeared in the middle of the road unintentionally revealed a mysterious plaster mine located just below the ground
Reportedly, the mysterious cave system mentioned above was discovered after Para Sapa Grotto - a group of adventurous people in the US explored the death pit in the town of Blackhawk. Accordingly, the Para Sapa Grotto team used a number of specialized tools for climbing and exploring caves to advance to examine the aforementioned death pit.
The death pit is quite large, located right next to a road leading into the residential area
Initially, the Para Sapa Grotto team thought that the giant crater could lead to a cave underground. However, as soon as they set foot beneath the crater, the Para Sapa Grotto team discovered that this is essentially a plaster mining system that was abandoned many years ago. Inside, there are still traces of mining, including large bores, or plaster debris.
Due to the relatively large crater, the Para Sapa Grotto team had to use specialized tools to explore the cave to descend.
Upon arriving, the Para Sapa Grotto group realized this was not a cave, but essentially a long abandoned mine.
The entrance to the mine is right below the death pit
This abandoned mine has an estimated length of 610m, width of about 45m, runs underground at least 12 houses
An old car in rust was found inside the mine. The mine may have been abandoned long before the Hideaway Hills residential area was built
The entire area of the mine has not been fully explored yet because the paths are collapsed, flooded or too dangerous to enter.
