The cave is one of the largest dry caves in the United States. Being a dry cave system means that the formations, such as stalactites, stalagmites, columns, and draperies are no longer actively forming. Even though the cave has been known about for over 100 hundred years it is still not fully explored. It is estimated that there are over 39 miles of tunnels inside the cave system. The 2 miles that are fully documented took 2 years to map and fully explore given the complexity of the cave system.

The cave was first created over a millennia ago. About 300 million years ago much of American Southwest was covered in water eventually the water began to recede throughout the years or eons of water erosion the cave dried out and became one of the largest dry caves of located in North America. Then in circa 900 AD a civilization lived and thrived in this region that is now known as the state of Arizona. They were the earliest inhabitants and were the Hohokam. They created a highly advanced and successful network of irrigation canals that stretched for more than 150 miles that was used for farming. Archeologists found evidence of the Hohokam using the cave as a temporary shelter. The cave was then “discovered” in 1879 by Solomon Lick who owned the area. While going around his property he discovered what he originally thought was a mine, that mine as it turns out was actually the cave system, we now call Colossal Cave. Though it was not always called Colossal Cave, when Lick first discovered it he named it “The Mountain Spring Cave” since it was discovered on Mountain Springs Ranch.
Legend of the Lost Loot
While the cave today is known for being a great tourist spot, in the 1800’s it was known for being a hideout frequently used by bandits. In 1887, the cave system played a major role in a story now called the “Legend of the Lost Loot”. The story tells of three men who robbed the Southern Pacific train twice over four months. They succeeded in stealing thousands of dollars, as well as gold and silver. It is rumored that the train robbers took upwards of $60,000, though Wells Fargo did not confirm how much money was stolen. The train robbers would likely have gotten away, even though they had left a blood trail out of the cave. They were only found because they bragged about their accomplishments. The bandits were then tracked by the Sheriff to one of the entrances of Colossal Cave. Once the Sheriff and the deputies found the bandits a shootout occurred, killing 2 of the train robbers. The lone survivor was sent to prison where he spent almost 2 decades. It is speculated that the train robbers hid the loot they stole somewhere in the cave before their deaths or capture. The survivor never revealed where the loot was hidden, which is how the legend got its name. Even today, people are still looking for the treasure hoping to stumble across it. This story did not just spark a great legend to tell tour goers it also gave the cave a nickname, Robber’s Cave.
Even though it is said the cave system was “discovered” in 1879, before that the cave system was used by native tribes over a thousand years ago. Artifacts as well as soot-blackened ceilings show that native people used the cave system in prehistoric cultures as well. According to some recent studies it is believed that the cave system also served as a shrine for the Ho’hokam people.
Colossal Cave was also used for other purposes as well. In 1905, a 75-foot tunnel was mined out in order to harvest bat guano. The bat guano was used as fertilizer.
Why Are There Pathways to the Cave?
The Great Depression actually contributed to the creation of the walkways that line the cave. In an effort to employ more people, the Civilian Conservation Corps hired people to create the walkways in the cave as well as the park roads around the area.
Bats in Colossal Cave Mountain Park
The area in and around Colossal Cave is home to many species of bats, 12 different species have been recorded to inhabit the Park, which is nearly half of the bat species found in the state of Arizona. Some bat species use Colossal Cave as a permanent home while others use it as a temporary home during certain times of the year. Some of the species you can find include the:
Townsend’s Big-eared Bat
Cave Myotis Bat (Threatened)
Mexican Long-tongued Bat (Endangered)
California Leaf-nosed Bat (Threated)
Western Red Bat
There is plenty of wildlife that can viewed when you visit Colossal Cave but one of the most notable animals that can be spotted is the coati. They are native to South America but can also be
found in Mexico, Central America, South America, and Southwestern United States. They have unusually long noses that can be used for searching for food and long tails which they have high up
in the air for balance. They have groups that can have up to 30 members.
