Securing Responsible Access to Threatened Caves

The Western Cave Conservancy is pleased to be the official host of the 2025 National Cave and Karst Symposium in Ely, Nevada. We look forward to meeting you in the Great Basin!

Cave Clean-up

The Western Cave Conservancy started with an idea: around 1994, Dan Syder suggested that the Mother Lode Grotto should start a cave conservancy in order to acquire a notable cave, Black Chasm, that was then available. That plan didn't materialize and Black Chasm became a show cave under private management. The cave wasn't acquired but its availability did provide the germ of a plan.

Fast forward a few years, to 2001 and the dot-com boom: Martin Haye received a windfall from the sale of a company he partially owned, and wanted to donate a nice chunk of it towards buying Rippled Cave. Originally, the idea was to have the Mother Lode Grotto do the purchase, but it didn't have the 501(c)(3) status needed for the donation to be tax-deductible.

As a result, a group of California cavers got together in 2002 to form the Western Cave Conservancy as an all-volunteer nonprofit, with an inaugural party at the 2003 NSS convention in Porterville, CA. We didn't have any caves yet, but we had a lot of possibilities...

From 2003 to 2005, a lot of research was done into possible cave acquisitions (mostly in California), but for a variety of reasons, none panned out in the short term. Keep in mind that in the West, a lot of karst landscape is on public land, rather than private. In keeping with our mission of "securing responsible access to threatened caves," this often means working with other land-management agencies to secure long-term access, rather than directly acquiring property.

Finally, in 2005, another potential buyer for Rippled Cave appeared, leading to the real possibility of losing access to the cave; this was the forcing factor that led the WCC to finally make its first cave purchase.

Also in 2005, the WCC was approached by cavers from the Diablo Grotto about the possibility of reopening and managing Windeler Cave, which had been sealed for years to prevent vandalism. This cave is located on USFS land, so a purchase was out of the question; after some negotiation, the WCC entered into an MOU to manage the cave for the Forest Service. (It took several years of work to reopen and re-gate the cave in a manner that ensured its safety; regular caver trips to this exquisitely decorated cave finally resumed in 2010.)

Threatened Caves

IXL Cave in California has suffered extensive damage over the decades.

Starting around 2004, the WCC got involved with trying to protect Avalanche Cave, a small but unique alpine cave in the northern Sierra Nevada. Many years of patient work with the Sierra Pacific Lumber Company and the USFS - plus some old-fashioned good luck - resulted in the Tahoe NF acquiring the land containing this cave (and several others) in 2016; this led to an official declaration by the USFS in 2018 that the cave would be freely available for responsible visitation.

Meanwhile, in 2010, the sale of a large tract of land near Davenport, CA to the Peninsula Open Space Trust and Sempervirens Fund opened the possibility of making legal access to some long-forbidden caves possible again. This took years of negotiation, but in 2014 the WCC signed an MOU with these organizations to allow limited visitation for research and mapping purposes; finally, in 2019, we were able to further expand this MOU to allow for recreational trips to these caves for local cavers.

In 2014, the WCC signed a lease for property containing Cave of the Catacombs, a small but historically interesting cave near Mountain Ranch, CA. In early 2020, we were able to purchase outright the bulk of this property, and continue to maintain a lease on the remaining area.

Shortly after acquiring Cave of the Catacombs, the WCC learned of another major karst property that was available for purchase: over 150 acres of karst and caves near Volcano, CA. Thanks to incredibly generous donations from cavers, we were able to successfully purchase this tract.

Lehman Caves

Lehman Caves, Great Basin National Park

Lehman Caves attracts tens of thousands of visitors to eastern Nevada yearly, a trend that began not long after their discovery in the late 1880s. For over 60 years, Lehman Caves National Monument protected these underground wonders, with their unique geology and ecology. And today, they remain protected as part of Great Basin National Park.

The 2016 NSS 75th anniversary convention in Ely, Nevada will include tours of this beautiful cave.

Symposium Merchandise

Troglodyte Playing Cards

We have no idea what these will look like yet, but we couldn't think of hosting NCKMS in Nevada without offering some themed-out playing cards. There's a good chance the card backs will feature a cave animal of the year, but we still have some time to figure it out.
