First of all, Colossal Cave is a large cave system in southeastern Arizona, near the community of Vail, approximately 22 miles Southeast of Tucson. Soloman Lick finds the cave in 1879. It contains about 3.5 miles (5.6 km) of passageways. As a result, temperatures inside average 70 degrees Fahrenheit (21 degrees Celsius) year-round.

In addition, the cave is an ancient karst cave, It is a “dry” cave. Additionally, the meaning of this is that its formations are completely dry, or “dead”, and do not grow. This is because the cave has water depositing limestone, but this source is no longer available. It instead feeds the “active” nearby Arkenstone Cave that continues to grow formations.

Finally, Colossal Cave is in use from 900 to 1450 AD by the Hohokam, Sobaipuri, and Apache Indians. Solomon Lick finds the cave in 1879. He is the owner of the nearby Mountain Springs Hotel. He is searching for stray cattle when he discovers the entrance to the cave. In addition, the cave is then in use as a guano source, and a tunnel, 25 metres (82 ft) long, was built in 1905. It produces a total of seven train cars of guano. The deposit plays out, and the tunnel is no longer in use.
