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

Dendrites 3Smudges 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:

Lynne has found this to be an excellent resource for all rockhounds, especially in Arizona.
