In 1952, two college boys searched the Black Hills looking for the perfect spot to build a summer cabin. Upon their search, they stumbled into the mysterious world of the Cosmos.
More about the Cosmos
The cosmos of the black hills was discovered by two college boys looking for a place to build a summer cabin. When they entered this area, they discovered something was off. The boys decided to camp out while investigating the odd phenomena. They came to a conclusion that there was something of interest to the general public, so they began to fix the cabin to make it safe, resulting in the demonstrations you will soon see!
