Mine Pit & Space Exploration

We went mountain biking at the new Cuyana mine trails this weekend. Great mountain bike trails built on and over mine tailings from long-abandoned iron ore mines. While there, I read about the use of one of these mine pits to test high altitude on humans. This was in 1957. Details here. The pit is over 400 feet deep. Today, it’s filled with water.
