The National Speleological Society is the largest organization in the world dedicated to the study and exploration of caves. We're a non-profit society and are affiliated with the American Association for the Advancement of Science. Our 10,000 members endorse a strong ethic of conservation and preservation of America's underground environments.
Every summer, the NSS hosts a convention where our members gather from around the world to collaborate and share information about trends in speleological science, art, literature, safety and techniques.
This fusion of science, art and social events is the highlight of our annual calendar.
The NSS has developed these brochures about the society, caves, and caving. You may freely download and print this material. Hard copies may be made available upon request.
Learn about the society's diverse programs, activities, and aspects of speleology in which members
are involved. Understand the benefits of membership in the society, and the value of membership to
caves, caving, and speleology.
This booklet discusses caves and the many elements of the sport of caving. Exploring caves is becoming
increasingly popular in all areas of the world, and caving responsibly is more important now than ever.
Discussions include safety, training, and learning to reduce the detrimental effect cavers can have on
caves and cave owner relations.
Caves are the world's most remote and fragile wilderness. They provide irreplaceable habitats for
rare plants and animals, some of which spend their entire lives in complete darkness. On its way
to our drinking supply, water often travels through caves into wells, springs, and aquifers, the
source of most of our drinking water. A cave's intricate passageways and dramatic formations offer
exquisite scenery and fascinating opportunities for research and mapping. Many caves also preserve
fragile prehistoric and historic records for millennia.
Lava tubes play important roles in our ecosystem, our history, and our culture. Caves formed in
lava are found where volcanoes have produced certain types of flowing lava - western United States,
Canary Islands, Italy, Japan, Korea, Kenya, Australia, Pacific Ocean islands, and other volcanic
hot spots. The islands of Hawaii harbor some of the world's most spectacular lava tubes.
Bats are among the most beneficial yet misunderstood mammals. They control insect populations,
pollinate cacti and tropical fruit trees, and are important to medical and scientific advances.
Sadly, bat colonies throughout the world are declining drastically as humans, intentionally and
unintentionally, endanger bats and disturb their habitats. Bats are extraordinary in a number
Information that can be passed out to cave owners, unaffiliated cavers, and others
to spread awareness of the issue. Participants at NSS conventions are required to
follow national decontamination protocols as specified by the USFWS.

Sitting at the intersection of the Western Shoshone and Southern Paiute homelands, Ely, Nevada encompasses only a fraction of the Native American regions that have been active in the overall region.
Today, four distinct reservations are active in the surrounding area: the Ely Shoshone, the Duckwater Shoshone, the Goshute, and the Utah Paiute-Kanosh Band.
Nevada is the most mineral rich state in the nation. Almost 80% of all the gold in the United States, comes from Nevada - which produces over 5 million troy ounces per year.
The Great Basin is one of the world's most prolific metallogenic provinces and produces about 11% of the total world production of gold. Additionally, this region is rich in silver and copper deposits. Total gold production from Nevada recorded from 1835 to 2008 totals over US $228 billion dollars at 2011 prices.
