Shoshone Cavern National Monument was the second national monument created in Wyoming and the only one in the state to be delisted and turned over to local government.

President William Howard Taft issued the proclamation creating the monument on September 21, 1909, just nine months after the cavern was discovered by Cody-area outfitter and rancher Ned Frost.

The cavern’s story offers interesting background for current debates over whether public lands in the West are best managed by local or federal governments. For four decades, the cave was managed by the National Park Service. In 1954, locals persuaded Congress to turn it over to the City of Cody, Wyo. After years of neglect the site passed back into federal hands in 1977, where it remains and is administered by the Bureau of Land Management.

Discovery

The cave was discovered by a man and his dog. Located on the east flank of Cedar Mountain, about five miles west of downtown Cody, the entrance was hidden below an outcropping.

One cold January afternoon in 1909, Frost was hunting on the mountainside—federally owned public land—accompanied by a large retriever. A bobcat, escaping from Frost’s hunting dog, darted down the entrance with the dog in hot pursuit. Frost followed, soon discovering that he lacked sufficient matches to see much beyond the “great room” just beyond the cavern’s entrance. Inside, he saw the first of what turned out to be hundreds of rooms linked together with tunnels. As a later visitor observed, the cave featured “a carnival of color running from red to purple, blue to yellow, brown to orange.”

The day after his discovery, Frost reported his find, and, a few days later, an exploration party including Cody’s founder and world-renowned showman, William F. “Buffalo Bill” Cody, inspected the cavern with lanterns and ropes. The cavern, in the view of Col. Cody and other visitors, warranted federal designation. Just nine months later, President Taft set it aside under the Antiquities Act.

The site was initially named Frost Cave, in honor of the discoverer, but the federal government believed the name implied cold temperatures in the cave, and suggested Crystal Cave as an alternative. Because of the proximity to Shoshone Canyon, a compromise resulted in the Shoshone Cavern name.

U.S. Department of the Interior.Surveyed to more than 4,000 feet below the entrance point, some experts believe the cave descends far deeper, perhaps running under the Shoshone River just north of Cedar Mountain and into the base of Rattlesnake Mountain to the north of the river. Geologists say the cavern was formed by hydrogen-sulfide-rich water, ascending aggressively inside cracks of the mountain, and creating crystalline encrustation on the cave’s walls.

National Park Service administration

The National Park Service administered the cavern, along with the 210-acre site surrounding the entrance, from 1916, when the NPS was created, until 1954.

The cavern entrance, at an elevation of 6,300 feet–about 2,200 feet above the road along the floor of the Shoshone River canyon –made public access to the site difficult. In 1934, crews from the Civil Works Administration graded a narrow but passable automobile route that switchbacks up to the cave entrance. Even after minor improvements over the next two decades, the steep climb did little to encourage tourists to drive the road to the site.

Over the years, Park Service officials viewed the cave as interesting, but not as compelling as other NPS-administered caves such as Carlsbad Caverns in New Mexico or Wind Cave in South Dakota. The Park Service did little to resist the efforts of Wyoming advocates for “return” of the cave to local government. Some advocates said that future management of the site would be a test of whether public lands could be better administered by local and state government than by the federal government.

Delisting the monument

Amid great fanfare, Congress passed an act in 1954 delisting the monument and returning the site to local administration. On May 17, 1954, after many years of lobbying by Cody boosters who contended that the site could be better run if it were not in federal hands, the federal government turned over the site to the City of Cody. The site was renamed Spirit Mountain Caverns, based on a mythical tale of Indian observances in or near the cave.

But the city and private concessionaires slowly came to realize that that the task of improving and operating such a site was beyond their means and expertise. Local businessman Claud Brown leased the cave from the city, formed a corporation and sold stock to 300 shareholders. He planned to open the cave to tourists the following summer, charge a fee of $1.50 each and sell snacks and souvenirs. Work proved difficult and expensive, however, and the grand opening did not come until September 1957.

Brown made improvements, paving the parking lot and stringing electric lights in the cave. He announced plans for a $190,000 cable car to the site but was unable to raise the money. And tourists mostly stayed away.

Brown operated the site until the late 1960s when the cave was entirely abandoned. Another group signed a lease in 1972 but did nothing more. The Cody City Council allowed for the cavern and the site to be returned to federal ownership in September 1977. After that, the location was incorporated into surrounding federal lands and is currently administered by the U.S. Bureau of Land Management.

Experienced cavers may access the entrance to the cave, now sealed by a padlocked gate, through application to the Cody office of the BLM. Bureau officials say Spirit Mountain Cave, as it’s now generally called, draws 600 to 700 spelunkers per year.

The primary historical significance of Shoshone Cavern National Monument is that it was one of the few national monuments ever to be delisted. The fate of the cavern, practically forgotten today, is one example that argues against the proposition that public lands would be better served if they were overseen by local governments or private owners, a result entirely contrary to the assumptions of those who sought the delisting.

— For more on this topic, read the book Cody’s Cave; National Monuments and the Politics of Public Lands in the 20th Century West, by Phil Roberts, Skyline West Press. The following is an excerpt from the book’s acknowledgements:

This book examines how national monuments were established, how federal agencies managed the operations, and how, in a few cases, the monuments were dropped from the system — delisted and sometimes forgotten. Shoshone Cavern National Monument  is used as an example of how government agencies, politicians, and the general public played key roles in a monument’s existence. This is a history, but also a cautionary tale for those who believe that national monument status permanently protects a resource. Political attitudes change about particular monuments or the programs in general — about the role of government in operating national monuments or about spending public money for such purposes. Just because a monument exists today doesn’t mean it may be there tomorrow — or forever.

  1. Those of us who came of age in Cody in the middle third of the 20th century know Frost Cave well. I remember sitting in the family station wagon driving up that awful road to take Claud brown’s tour. He’d built illuminated boardwalks, stairs, and ladders, and lowered an air compressor down into the depths to extend the breathable atmosphere for his nicotine-loving patrons. Tourists were able to venture a few hundred feet down into the many caves and passageways. Later as teens we would use spools of kite string to leave a navigation followback line down into the Earth’s bowels , and get all the flashlights and batteries we could carry and start down…down…down , even using some ropes. It would’ve been very easy to get lost down there because there were passages in all directions. We heard water in the walls , but it became obvious the lower levels were dreadfully short of oxygen and long on stink. I’m convinced those caves run down as far as the river , where there is a geothermal zone . I have never heard from anyone as to the extent of exploration and mapping of that network of caverns , but teams of cavers have gone a long ways inside Spirit Mountain , which is for all practical purposes hollow.

    One other anecdote. Claud Brown wore many hats, one of them being a very strident Rockhound. He had a rock shop and curio store back in Cody alongside his wife’s fur salon ( go figure) . When he pulled out of the Spirit Mountain concession business, he plundered the mountain . Truckloads of crystals and fossils were hauled to town to be sold . One in particular: a giant Ammonite fossil alleged to be the largest in the world. It was right alongside the road with its own signage, a 2-foot diameter spiral nautilus-like shellfish in stone. When Claud brown left the mountain , that Ammonite just disappeared. I doubt that is coincidence , given all the other fossils and mineral specimens that showed up in his rock shop.

    Lot of history up there, going back millions of years. It’s amazing more people didn’t die in those caverns, since Spirit Mountain cave was also a well know party place in my younger days. The BLM locked the main entrance, but there are other ways into the mountain. Oh by the way , the other mountain across the river, Rattlesnake Mountain , had many small caves on its south facing slopes above the river, and those caves were inhabitated by Pre-Columbian native people, and later the Sheepeater culture. Archaeologist George Frison had his students excavate a couple caves I found over there when I was 14 and reported to the late hisotirian Bob Edgar, who in turn contacted his friend Frison. But that is another story.
