We know that NSS grottos are frequently challenged to find engaging material for their newsletters. Most of us have been there and we get it...
The 2016 convention team would like to share some material with our friends across the country about our plans for the 75th anniversary celebration of the NSS. Over the next several months, we'll post some material here that is free for any internal organization of the National Speleological Society. All we ask is that you include the credit information contained in the material. Many cavers have contributed to this collection and we'd like to recognize their efforts.
If your grotto publishes digitally, please consider linking to our website or including our convention's hashtag in your post (#NSS75th). And, if you're willing to share, we'd love a copy of your newsletter for our records. Thanks!

With more than 120 mines, Nevada is one of the country's major producers of turquoise. Most is found as nuggets, fracture fillings and in breccias as the cement filling interstices between fragments. Some of this unusually coloured turquoise may contain significant zinc and iron, which is the cause of the beautiful bright green to yellow-green shades.
Major turquoise deposits in Nevada occur along a wide belt of tectonic activity that coincides with the state's zone of thrust faulting. It strikes about N15°E and extends from the northern part of Elko County, southward down to the California border southwest of Tonopah.
