The underground fleet
There is perhaps no more legendary vehicle on the American road - and off of it - than the Jeep. The rugged four-by-four that built a reputation for performance and reliability during World War II found civilian duty after the war, navigating the hills, forests, and highways of America. And a handful went undercover to become what may be the nations largest fleet of underground Jeep. These eight Jeep pull trams that carry visitors through Fantastic Caverns, just northwest of Springfield, MO.
The History of the Jeep
The Jeeps at Fantastic Caverns are descendants of those that earned their stripes on the battlefields of World War II. More than 600,000 Jeeps were built by Willys and Ford during the war. Developed for the military on the eve of the conflict, the Jeep got its name, so the story goes, from "general purpose" or GP. But the term "Jeep" had already been in the vocabulary of Army slang for years, according to one account.
Citing a 1941 Army report, Jim Allen wrote in Fourwheeler magazine that the word "Jeep" was used by Army mechanics as early as World War I to refer to any new motor vehicle that was brought in for testing. "Jeep" was also derogatory for a new recruit. The name was even given to a comic strip character - Eugene the Magical Jeep, a small, endearing, doglike creature who had mysterious powers and first appeared in "Popeye" comics in 1936.
Taking a cave tour by Jeep today
The Jeep has come a long way - literally - since those days, and the fleet at Fantastic Caverns is no exception. Collectively, the vehicles that ferry visitors through the cave have logged thousands of miles. It's been slow going, too. The cave Jeep's average speed is just under one mile an hour - it takes about 55 minutes to complete the leisurely one-mile cave tour. The odometer on each vehicle clicks an average of just 150 times each year.
Unlike their military and civilian cousins, these Jeeps don’t spend much time contending with mud, snow, ice or blazing summer heat. The temperature in the cave, which is open all year, hovers around a mild 60 degrees during all seasons.
Preserving their historic reputation as a workhouse, the Jeep, provides an innovative way to see one of the country's most accessible tourist attractions. There's no walking necessary, so the tour is ideal for families with small children, older folks and people with physical limitations.
Headlights on the Jeep, are fully functional, but they're seldom needed. The entire tour route through the cave is brightly lit so visitors can see the stalactites, stalagmites, flowstones and other formations that took countless generations to form.
The Underground Fleet at Fantastic Caverns
The Jeep-drawn trams are a less invasive way for guests to see the cave. The vehicles' eight wheels on the cave floor are far less disruptive than hundreds of walking feet. The Jeep, also run on propane, a cleaner-burning fuel. Taking care of the environment is important to the owners of Fantastic Caverns. Water quality is closely monitored - its purity is vital to wildlife, including the tiny, rare, blind cavefish - that inhabit the underground ecosystem. Great care is also taken to protect the cave's ancient, irreplaceable formations from damage.
