This outreach event will likely include many of the federal agencies with whom the NSS holds working arrangements across the country. Both the Bureau of Land Management and the United States Forest Service have large district offices in Ely, and Great Basin National Park is just a short drive away
Of course, since our 2016 convention coincides with the 100th anniversary of the National Park Service, they'll probably join the party as well!
To close out the day, the producers of the IMAX film "Journey Into Amazing Caves" have given us permission to share that film with the residents of Ely. NSS cavers (and stars of the movie) Hazel Barton and Nancy Holler Aulenbach will be on hand to join the festivities.
If you'd like to join our production crew, we could definitely use some extra help! We specifically need help in project management, grant writing and community relations to accomplish this task.
If you're able to help us as a volunteer or as a team leader, send an e-mail to firstname.lastname@example.org.
Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb2S3. This soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony. The name is from the Greek stibi through the Latin stibium as the old name for the mineral and the element antimony.
Stibnite has a structure similar to that of arsenic trisulfide, As2S3. The Sb(III) centers, which are pyramidal and three-coordinate, are linked via bent two-coordinate sulfide ions. It is grey when fresh, but can turn superficially black due to oxidation in air.
Pastes of Sb2S3 powder have been used since ca. 3000 BC as eye cosmetics in the Middle East. It was used to darken the brows and lashes, or to draw a line around the perimeter of the eye. Antimony trisulfide finds use in pyrotechnic compositions, namely in the glitter and fountain mixtures.
