A Thrilling Experience at Cosmos Mystery Area

History
The history of this place is as unique as the place itself. In 1952, two college boys searched the Black Hills looking for a perfect spot to build a summer cabin. While exploring, they stumbled into the mysterious world of the Cosmos. This area is the strangest location in the entire Black Hills.
The old cabin areas in the Cosmos Mystery Area especially piqued their interest as logic and physics laws seemed to be turned upside-down. However, they continued to experiment and develop the demonstrations until they eventually opened their discovery to the public in 1953.
Geode Mine
This is one of the famous spots at Cosmos Mystery Area. All you have to do is pick up a hand spade and start digging for your very own geode. Once you find a keeper, take it over to our special hydraulic press to crack open your newly discovered treasure. You will be amazed at the beauty of the naturally formed crystals inside.
Mystery House
The Mystery House provides a one-of-a-kind experience that will create unforgettable and fun memories. Once you enter the Cosmos Mystery Area, everything will be unique and weird, leaving you spellbound. Water flows uphill, tall people appear shorter than their smaller friends and what seems to be measured level is not. When you go further inside the Mystery House, you will have a chance to walk up a wall, be mysteriously pulled sideways when hanging perfectly straight from a rafter, and experience other incredible physical forces and demonstrations that can only be seen at the Cosmos Mystery Area.
