Why are there no entries for caves in the Geographic Names Information System Database?

Geographic Names Informations System (GNIS) entries for caves are in the database but cannot be retrieved on the public website. In response to the 1988 National Cave Management Resources Act, Department of the Interior Regulation 43 (CFR Subtitle A, Part 37) forbids the release of information regarding the location of all caves on Federal lands.

Currently, the GNIS database is not able to distinguish between caves on Federal lands and caves that are not on Federal lands, so no features classified as “cave” can be retrieved on the GNIS database website. 

Information regarding the location of caves in GNIS can be requested in writing from the office of the Secretary of the Interior. Each request will be analyzed on a case-by-case basis. Mail requests to: 

U.S. Department of the Interior, Secretary of the Interior
1849 C Street NW
Washington, D.C.  20240

Can you feel an earthquake if you're in a cave? Is it safer to be in a cave during an earthquake?

There is nothing different about a cave that would make it immune to the shaking from an earthquake. Just as there are safer and less safer places to be on the surface of the earth during an earthquake, there are also various characteristics inside caves that make some cave locations safer or less safe than others. First of all, whether or not you...

Why are bats important?

By eating insects, bats save U.S. agriculture billions of dollars per year in pest control. Some studies have estimated that service to be worth over $3.7 billion per year, and possibly as much as $53 billion. This value does not, however, take into account the volume of insects eaten by bats in forest ecosystems and the degree to which that...

What should cavers know and do in regard to White-nose Syndrome?

In response to White-nose Syndrome (WNS), the U.S. Fish and Wildlife Service and individual states request that cavers observe all cave closures and advisories, and avoid caves, mines or passages containing hibernating bats to minimize disturbance to them. The Service asks that cavers and cave visitors stay out of all caves in the affected states...

What is White-nose Syndrome?

White-nose syndrome is an emergent disease of hibernating bats that has spread from the northeastern to the central United States at an alarming rate. Since the winter of 2007-2008, millions of insect-eating bats in at least 33 states and seven Canadian provinces have died from this devastating disease. The disease is named for the white fungus,...

Carlsbad Caverns - massive travertine speleothems

The massive travertine speleothems, particularly the great stalagmites of the Big Room, reflect the antiquity of the air-filled phase of the Caverns' history. The monumental stalagmites formed over tens of thousands of years, as water slowly dripped, splashed, flowed, and dried, leaving behind a trace of calcite (travertine) with each drop. Some of these massive

This passage near the entrance to Valentine Cave displays lines and ridges marking fluctuating levels of lava flowing in the tube. The ceiling above the highest lava flow level displays abundant lava-cicles. Lava-cicles form from either lava splattering and dripping from the ceiling or the melting of ceiling rock from the high radiant heat and hot vapors moving in the
