Big Warm Spring, Duckwater Shoshone Reservation

Two main warm spring areas are located near the small community of Duckwater, which is on the Duckwater Indian Reservation in northeastern Nye County. Big Warm Spring or Duckwater Spring is located in Sec. 32, Tl3N, R56E and has a reported temperature of about 32.5°C (Eakin and others, 1951; Mifflin, 1968; Van Denburgh and Rush, 1974). Little Warm Spring, in Sec. 5, Tl2N, R54E, is about the same temperature. Both springs rise in alluvium a short distance west of a north-striking, range-bounding fault (Stewart and Carlson, 1974). The area may have been called the Burrell Hot Springs district in the past. The water is used locally.

A geothermal catfish-growing facility was operated at this site, on the Duckwater Indian Reservation, between 1982 and the early 1990s. When in operation, over 136,000 kg of prime 0.2 kg catfish filets per year were produced (Geo-Heat Center Quarterly Bulletin, December 1992).

Cave ecosystems are often dependent on organic material carried in by water, which serves as the primary food source for the environment. In arid climates with minimal surface rainfall, the input of organic matter and nutrients into caves becomes limited, affecting the overall energy flow within these environments. The intricate interplay between surface conditions and cave biota presents unique management challenges for modern cave biologists. Image courtesy of Dr. Jean K. Krejca, Zara Environmental LLC.

Lily the Cave Bear

Cave Bear - Arctodus simus

Ely, Nevada's White Pine Public Museum features the skeletal model of a cave bear (Arctodus simus) that was discovered in a nearby cave in 1982. This extinct species inhabited North America during the Pleistocene epoch from about 1.8 Mya until 11,000 years ago. It was the most common early North American bear and is considered one of the largest known terrestrial mammalian carnivores.

The museum's collections also include an extensive mineral display of copper ore samples, petrified woods, and fossils of ancient marine life.

Symposium Merchandise

h2go Essen Vacuum Food Container

It's a double-wall, stainless steel, 17 oz capacity thermos from h2go®. This thing is more rugged than your cave pack! We've been trying to beat up the manufacturer's sample, but it keeps winning. Hot things stayed hot, cold things stayed cold... and ours will have cool cave art printed on it.
