Grand Canyon Caverns began forming 300 million years ago. The active phase of the cave was, when the nearby Grand Canyon had the same depth. The Colorado river is the sink of the groundwater, so the water table has about the same depth, slightly ascending with the distance. Today this depth is about 1,600 m (1 mile) below ground.
As the climate is semi-arid (dry) today and groundwater is deep below, there is absolutely no water in the Grand Canyon Cavern. It is extremely dry and thus definitly inactive, neither the cave nor the speleothems are growing. The only action that may occur (very rare) is a heavy rain outside, that reaches the cave. Because of the semi-arid climate this happens very seldom, and the effect lasts only for a limited time. The image on the right shows how dry this cave is. All animals that enter the cave by accident and die in this cave get mummified. This mummified bobcat is about 150 years old.
The cave was first known to the indigenous Hualapai Indians. Once during a heavy storm in 1917 two brothers died from flu nearby. Their companions were not able to dig graves in the frozen ground, and they did not want to bring the bodies back to the tribe, because they feared spreading the flu to the whole tribe. They buried the two dead inside the entrance of Grand Canyon Caverns, in a shaft they thought was 17 m deep. As a fact the floor of this shaft was a huge rock, which blocked the connection to the cave below. They never again visited the cave, as they believed it to be a sacred place because of the burial.
The cave was discovered by Walter Peck in 1927. He was on the his way to a poker game, and there he told the others about his discovery. The next day, he and some friends brought ropes and lanterns with them to explore the cave. One of the cowboys was lowered with a rope around his waist. While he was lowered he saw two skeletons and a saddle at a depth of about 17 m, but the rock which formerly blocked the shaft had fallen down since the burial. He touched the floor 46 m below the surface.
The first explorer saw sparkles on the rocks, but being just a cowboy he did not really know the origins. So he told his companions about the sparkles and soon they believed in a gold vein. Today it is obvious that this had only been reflections of calcite crystals. Walter Peck purchased the ground, as he planned to mine the gold. But the assay report of the collected rocks revealed only limestone and iron oxide. Walter Peck was pretty disappointed.
The first explorer had discovered the two bodies and the saddle. The saddle never made it into the newspaper, and so the bodies soon became the remains of prehistoric cavemen. Scientists came from the east to pick up and study the bones. Walter Peck had a brilliant idea, how to make a business of his gold-less gold mine. He charged 25 cents from visitors to see where the "caveman" had been found. They were lowered into the cave with a primitive elevator built of wood and ropes, but they had to bring their own light.
The depth of the cave was the biggest problem for commercializing it. With the rope, only one person at a time could enter the cave. A wooden stair was built by the Civilian Conservation Corps (C.C.C.). In order to employ the many people out of work during the depression, they made a deal with Walter Peck: they built the entrance for free, but he had to provide the material.
This stair allowed larger groups of visitors, but the height equals a 17 stories building, so only the fittest could visit the cave. So the construction of an electric elevator started. A 64 m deep shaft was blasted into the limestone, which took two years. The installation of the elevator took 18 more months. Since this time the elevator takes the visitors down to the floor level of the cave. And finally the location of the dead bodies was sealed off forever, as requested by the Hualapais.
In the recent years the operators have extended their tours including two cave trekking tours, the motel was extended, there is now a campground, RV and cabins, and a restaurant. Also there is now a small restaurant named Cavern Grotto seating 16 person inside the cave. It is possible to stay over night in The Cavern Suite. This is probably the only hotel room which is 120 m long, 60 m wide, and 20 m high. It works rather well as the humidity is very low and the temperature is rather high for a cave. The guided cave tour is included with the room.
