Timely Tips
Club member Lynne Wheeler has always been a great source for tips when it comes to collecting, cleaning and storing your precious finds. You can repurpose many household items, such as:
Plastic water jugs (to store rocks); food containers (best if they are clear); desiccants (to help preserve humid-sensitive rocks like halides/halites); egg cartons, bubble wrap, and cotton stuffing from pill bottles (to protect fragile items you find in the field); small boxes; plastic bags; and more. So before you dispose of your garbage, take one last look and make sure you can’t use it on your next field trip.
Dendritic Patterns
Smudges do not count! Dendritic patterns must show a clear fern or tree-like pattern.
For more information on dendrites and much, much more, Lynne Wheeler highly recommends:
Collecting Rocks, Gems and Minerals
by Patti Polk
ISBN-13:978-1-4402-0415-90
Lynne has found this to be an excellent resource for all rockhounds, especially in Arizona.
Sonoranite — The World’s Newest Gemstone
While in Tucson in 2019, members Lynne Wheeler and Peggy Randall had a fascinating conversation with the folks at Sonoranite
You can see from the photo that Lynne took and from the gorgeous jewelry shown on the Sonoranite website, this Arizona desert gemstone is an incredible find!
