Nevada's Great Basin region contains the most active geothermal field in North America. The same geomorphology that created the basin and range landscape has caused Earth's crust to be very thin in this area. This close proximity to subsurface magma pockets allows super-heated water to form hot springs across the region.
The information on this page should be used with care. Not all hot springs are really hot (some are just in the "warm" category.) Other springs can be scalding and physically dangerous. The information provided here is simply meant as a reference. Do your own research and proceed with caution!
Click on the following map icons to get more information about each hot spring. The locations marked with red stars tend to be the most popular and accessible. Locations marked with an orange dot have extended descriptions available. Locations with a blue dot only have geochemical data. Most of the minor locations haven't been field-checked in years, so do your own research before you head out. Not all hot springs are suitable for public soaking. Use your own discretion.
Azurite is a soft, deep blue copper mineral produced by weathering of copper ore deposits. The mineral, a carbonate, has been known since ancient times, and was mentioned in Pliny the Elder's Natural History under the Greek name kuanos. While not a major ore of copper itself, the presence of azurite is a good surface indicator of the presence of weathered copper sulfide ores. It is usually found in association with the chemically very similar malachite, producing a striking color combination of deep blue and bright green.
The intense color of azurite makes it a popular collector's stone. However, bright light, heat, and open air all tend to reduce the intensity of its color over time.
