Epidote and Mica (just to name two!)

An Epidote vien.  Dammit Jim, I'm a gemologist, not a mineralogist!
Beside a small river and exposed partially from a road cut, there are small veins of Epidote.  At first the epidote looked like it had formed with garnet and quartz, but after doing some research, it could also be the red epidote "piemontite".  Epidote appears to be fairly common, but I have read that light yellowish green and reddish colors are more rare.  I have found small quantities of both those colors and "black" epidote.
The outer "layer" of this crystal has been severely eroded,
but you can still see the nice light green color.

Another attempt to capture beauty without proper camera skills.
This crystal is actually a more brilliant color of green.

Epidote has been included in the mythology of various cultures, including the Greeks, Norse, and Native Americans.  Metaphysically, it appears to be used for spiritual growth grounded in earth energies, and is thought to be an overall positive and balancing stone.

Nothing like fresh mountain peppermint and sage to make prospecting for the epidote an uplifting and pleasurable experience.

I also found some mica of interesting color.  These pieces were picked up off the ground. There are very nice formations of mica "clusters" throughout the face of the rock.  Mica is one of the names for "Coyote" in the Sioux languages.  A trickster that creates a story out of our experiences and reflects them back to us in such a way to cause us to make sense of them.  Fitting for this highly reflective mineral.

"Huh?" - Yes, it is blue, red, and purple.  I believe it is some form of lava rock ... aren't they all?!

Oh, I almost forgot ... the salmon were spawning ...

Prospecting Adventure (an introduction)

The Salmon River in Idaho, USA
My name is Michael Brandon, G. G. S.  I am certified as a Graduate of Gemological Sciences from the Texas Institute of Jewelry Technology - - my intention is to share information and continue to learn information about not just gems, minerals and the many opportunities they may provide;  but also to share the wonders and the rawness of the journeys that lead to that star sapphire, ruby ring, or sometimes just to witness the treasure of nature's beauty.  Ah, now there's a thought ...

I've spent this last spring and first half of the summer camping out in the "Gem State".   It was an unusually wet spring this year.  The creeks and river were flooding and at first I wasn't real sure where I should start to look for gems.  Don't get me wrong, I'd love to find some gold, too.  I talked to some people in the various towns and communities about places that would be good to look for gems and tried to figure out what exactly could be found.  For the most part, people have been encouraging and informative.
Purple (possibly "Star") Sapphires from my first "dig".

Now that the rains have died down I have been digging, with permission, in the tailing piles of an old gold mine and at various other places within an hour's drive of where I am located.  I do not have my lab equipment for identifying gems and minerals yet, so I have found interesting specimens of as yet unknown identity.  Most of the specimens are simply found on top of the ground.  I was told that a lot of prospectors who have come through this region were only looking for gold, or just didn't know what the other minerals and gems were.  I have found  small pieces of "golden", pink, blue, purple, and star sapphire; a variety of garnets, serpentine, calcite, a nice piece of jasper, blue chalcedony, small and large clear quartz points, and a quartz point that appears to turn from smoky to citrine.   I have also found nice specimens of mica and other as yet unidentified minerals.  Later, when I have tested everything, I will update the unidentified minerals with their proper identification.

One great thing I have learned about prospecting is that when you are on your hands and knees in the dirt you begin to notice many different things besides rocks.  I have enjoyed learning the characteristics of certain insects and animals.  I have started to learn more about edible and medicinal plants since I have started camping and hiking more.  My conversations at the coffee shop have started to turn into mineralogy and mining study groups.  I finally figured out how to harvest some nice morel mushrooms.  Well, you get the picture.

I'm deepening my knowledge about indicator minerals for gemstones as well as geological formations and interactions.  There are limestone, granite, and basalt coming together in many places here.   I am collecting micro mineral specimens, and will be putting together some kind of website for my mineral collection in the future.  I am also interested in faceting and lab work.

You never know what I may be able to "gather" for you.  One thing I have learned, is that only reported minerals of specific locations are researchable through non-local resources.  In other words, not all found minerals have been reported to the government or mineral societies.

The first few posts in this blog may be a "catch up" of some of my recent prospecting adventures.
