Wind Cave National Park: A Cave With a History Worth Getting Lost In

Our family loves caves. I grew up making the pilgrimage to Mammoth Cave with my parents, so when Wind Cave National Park showed up on the itinerary, there was no debate. It was a foregone conclusion. A non-negotiable. A hill I was willing to die on — preferably underground.

Wind Cave is the sixth largest cave system in the world, with more than 30 miles of passages still believed to be unexplored. Here's the kicker: it's only the second largest cave in South Dakota. Jewel Cave beats it. We'll get to that one another day, but for now, let that sink in — South Dakota is just sitting out there, quietly hoarding caves.

Above ground, the park is home to a surprisingly diverse ecosystem of wildlife and wide-open prairie. But we'll get there. First, let's go underground.

History

The cave was originally known to the Lakota tribes of the Black Hills, who considered it a portal to the underworld. Honestly, given what's down there, that tracks.

The modern discovery story has a nice bit of slapstick to it. In 1881, Tom Bingham was walking past the cave's entrance — an 8-by-10-inch opening in the ground — when the cave exhaled and blew his hat clean off his head. He came back later to show his friends. This time, the cave inhaled and sucked his hat back in. That's because Wind Cave is what's known as a breathing cave: it inhales and exhales based on atmospheric pressure differences between above and below ground. It's the geological equivalent of a living thing. A very dark, very old living thing that will absolutely take your hat.

First Explorers

A few days after Bingham's involuntary hat trick, Charlie Cray armed himself with a candle and a ball of string, squeezed through the opening, and became the first known person to enter the cave. What he found inside — intricate formations unlike anything described before — would eventually be named boxwork, a formation so rare it's only found in a handful of caves worldwide. More on that later.

Years after Cray, Frank Herbert led a more organized expedition, though it took his entire party a full day just to relocate the entrance. They didn't have GPS back then. Honestly, respect — finding a hole that size in open prairie without a pin drop is legitimately impressive.

The Binghams eventually returned, widened the entrance, and built a cabin directly over it — using the cave's natural airflow as a free HVAC system. Warm in the winter, cool in the summer. They were accidentally ahead of their time.

In 1889, the mineral rights were sold to the South Dakota Mining Company, and the McDonald family — J.D., Elmer, Alvin, and Mary — took over operations. South Dakota winters are long. We're talking really long. The kind of long where you look at a hole in the ground and think, "yeah, let's see where that goes." The cave gave them something to do.

Alvin McDonald

Alviiiiiiinnnnn! No, not the chipmunk.

Alvin was one of the younger McDonald brothers, and the cave got into his blood in a way it didn't for the others. He became the first person to systematically explore and map the cave — his goal being to find the end of it. That goal has not been accomplished to this day. Independent organizations are still working on it.

Here's the part that gets me: imagine you're a modern cave explorer. You've got headlamps, GPS, climbing gear, a whole team. You round a corner into what you are certain is virgin passage — untouched, unseen, undiscovered. Your heart is pounding. You're about to make history. You raise your light to the wall and there it is.

Alvin's signature.

The guy did it in the dark. With a candle. In the 1880s. You didn't discover anything. Alvin was already here.

In 1890, with the mining company no longer paying the family (turns out there's no gold in Wind Cave — just cave), Alvin started offering tours. He had a habit during those tours of disappearing any time he spotted a new hole to squeeze into. Minutes. Sometimes hours. Guests waited in the dark — and I mean that literally. They had candles. An hour of light, maybe less. At some point the math stops working in your favor and you're just standing in a hole in the ground hoping the guy with the map comes back before everyone's candle goes out.

Guests apparently just waited. Different era.

Alvin took a collection of cave specimens to the 1893 Chicago World's Fair. He contracted typhoid fever not long after and died on December 15th, 1893. He was 20 years old.


Beyond Alvin

After Alvin's death, things got complicated. The McDonald family had been operating under the mining company's umbrella until the company stopped paying — at which point they assumed ownership. They brought on the Stabler family as partners. What followed was a series of court cases among the Stablers, the McDonalds, and the SD Mining Company.

The verdict: the mining company had no rights to the property. The McDonalds couldn't prove their homestead claim. The Stablers had no standing either.

So the U.S. government did what governments do: claimed the property. In 1902, Wind Cave became a national park — the seventh in the country and the first established to protect a cave.

Building the Park

The park saw modest improvements over the following decades until 1934, when the Civilian Conservation Corps arrived and got to work. The CCC paved trails inside the cave, improved park infrastructure (roads, water, sewer), constructed new buildings, and began work on the first elevator shaft — making the cave accessible to visitors who couldn't exactly shimmy through an 8-inch hole. The elevator has been remodeled three times since. There was some trial and error involved. It was the first of its kind.
