Across 75 years, the NSS has enjoyed some dramatic accomplishments! Cavers in the society have led efforts nation-wide, and even globally, to further our knowledge of caves and caving techniques and to push the boundaries of underground exploration. The unfortunate part is that nobody really made an effort to write everything down - we just did it!
The 2016 convention staff is planning to crowd-source our own backstory. We know the knowledge exists in all grottos of the society, but we need to work on gathering it in one place. If you would like to help recruit, organize and fact-check pieces of our history into a consolidated timeline, we would love to have you join the team!
This is worth doing.

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.
