Description

What is Jewel Cave: No End in Sight?

Jewel Cave: No End in Sight is an 88-page, full-color softcover book about Jewel Cave National Monument, published in 2022 by the Black Hills Parks & Forests Association. The lead author is Arthur N. Palmer, a retired professor at SUNY Oneonta who has spent about 45 years studying caves and karst around the world. Co-authors include Mike Wiles (the National Park Service physical scientist who has surveyed Jewel Cave for decades), Dr. Andreas Pflitsch (cave climate research), Dr. Hazel Barton (cave microbiology), and Dr. Olivia Hershey. Joanna Marshaus designed the book and Ed Fischer edited it.

The title is the literal point of the book. As of 2026, surveyed passage in Jewel Cave is past 220 miles, making it the third-longest cave in the world after Mammoth Cave in Kentucky and the underwater Sistema Sac Actun in Mexico. Volunteer survey teams keep adding miles every year. Airflow and barometric data suggest the mapped passage is a small fraction of what is down there. The book lays out the evidence for why exploration has, in fact, no end in sight.

What’s inside

This is a geology book that respects general readers. Palmer wrote it so a park visitor with no background in earth science can follow the argument, and so a working cave researcher can use the same pages as a current reference. The chapters cover how Jewel Cave formed, what makes its dogtooth and nailhead spar calcite different from formations in nearby Wind Cave, what the cave’s airflow tells researchers about hidden volume, the unusual microbial communities living on the walls, and the survey history from Frank and Albert Michaud’s 1900 discovery through Jan and Herb Conn’s 1960s-70s survey work to the post-2014 Splinter Section breakthroughs.

• The geologic origin of Jewel Cave and how it differs from Wind Cave, 14 miles away
• Dogtooth spar, nailhead spar, boxwork, cave bacon, hydromagnesite balloons, and other Jewel Cave formations explained in plain language
• Cave climate and airflow research that suggests the surveyed cave may be only 5 percent of the actual system
• Microbial life in the cave, including extremophile organisms with potential medical research interest
• Survey history and how the cave grew from less than 2 mapped miles in 1959 to 220+ today
• Photography from passages well beyond the public Scenic Tour, including remote survey camps

Who is this for?

Visitors who took the Scenic Tour and want to know what they actually saw. The Scenic Tour shows about half a mile of paved walkway. The book gives you the rest of the story: how those calcite crystals got there, why one chamber has boxwork and the next does not, what happens past the elevator shaft. If you came out of the cave with questions the ranger did not have time for, this is the answer.

Geology students, earth-science teachers, and working researchers. Palmer is one of the most-cited cave geologists alive, and his textbook Cave Geology is the standard graduate reference. No End in Sight pulls his Jewel Cave research into a format you can hand to an undergraduate class or use as a field-trip companion.

Cavers and survey volunteers. If you grid-track survey reports, follow the Jewel Cave volunteer survey project, or have ever wanted to read what Mike Wiles thinks about the airflow data, this is your book. It is also a respectful introduction for non-caver friends and family who want to understand why you spend long weekends underground.

Gift buyers for the science nerd in the family. At $19.99 with the BHPFA member discount, this is a solid under-$20 gift for someone who reads non-fiction, watches caving documentaries, or visited Jewel Cave on a Black Hills road trip.

Frequently asked questions

How long is Jewel Cave?
Surveyed passage is past 220 miles as of 2026, with new miles added regularly by the volunteer survey team. That makes Jewel Cave the third-longest cave in the world. The book explains why airflow and barometric data suggest the surveyed cave may be a small fraction of the total system. The current NPS survey number is at nps.gov/jeca.

Is this book the same as Jan and Herb Conn’s “Jewel Cave Adventure”?
No. Jewel Cave Adventure (1977) is a memoir by the Conns about their early survey work in the 1960s and 70s. No End in Sight is a 2022 geology book that draws on the Conns’ work but covers the science of the cave: how it formed, what is in it, why it keeps growing. The two books complement each other rather than overlap.

Do I need a geology background to follow it?
No. Palmer wrote the explanations so a general reader can follow them. Technical terms are defined in plain language the first time they appear. If you took high school earth science once, you have enough background.

Who is Mike Wiles?
Mike Wiles is the longtime physical scientist at Jewel Cave National Monument and one of the principal volunteer surveyors of the cave. If you have read NPS survey reports or seen the news coverage of Jewel Cave passing 200 miles in December 2018, that was Mike’s team. His chapter on airflow research is the load-bearing argument for the book’s “no end in sight” title.

Is the book sold at Jewel Cave’s visitor center?
Yes. BHPFA is the cooperating association that runs the Jewel Cave park store, and No End in Sight is stocked there along with our other Jewel Cave titles. It is also available through this online shop.

Does buying this support national parks?
Yes. BHPFA is the official nonprofit partner of Wind Cave National Park, Jewel Cave National Monument, Scotts Bluff National Monument, and Agate Fossil Beds National Monument, as well as the Black Hills National Forest and Nebraska National Forests & Grasslands. Proceeds from every purchase support education programs, conservation projects, and visitor services at these sites. Because BHPFA is the publisher of this particular book, the proceeds-to-park ratio is unusually direct.

Can I get my Passport book stamped at Jewel Cave when I pick this up?
Yes. Jewel Cave National Monument is an NPS site with a Passport to Your National Parks cancellation stamp. The visitor center has the stamp, and Passport books are available for purchase in the same park store.
