I found this at the SF Gem and Mineral Show yesterday. It's almost a local specimen.
Cowboy Mine
Wellington Hills
Lyon County, Nevada
The andradite xls are well formed and associated with epidote and quartz.

Nice specimen Barbra. It has additional interest for me because my wife's from Lyon County, NV and one of her friends sent me the specimen below saying only "Nevada Garnet." I've wondered about the ID and source so I'll do some more checking on the Cowboy Mine.

Are those garnet xls sitting atop epidote and quartz?

I'm not sure of all the minerals in the groundmass. There's quartz, certainly, but no epidote that I can see. The s.g. is very high. It hefts like some of the metallic ores but that could have many causes. It's a mystery specimen at this point.

There are lots of cool secret places all out and about in Nevada with all sorts of minerals and metals but PLEASE!!!! if you go on a field trip watch where you are walking as there are thousands of open vertical mine shafts and/or partially covered mine shafts that will instantly give-way under your weight.
Never enter mine-shafts unless you are fully qualified to test the air and the support structures.

If you are not a Mine Engineer then you best stay out.

You also need to now what raw arsenic looks like, raw mercury looks like and also know your poisonous snakes and what they look like and where they usually hang out during daylight hours and where they hang out during night time hours.

When traveling the outback of Nevada there are places where no cell phone coverage is and you need to make sure you carry plenty of food and water just in case you have car/truck trouble.

I have traveled thousands and thousands of miles in the outback of Nevada and it can be very unforgiving to those who do not think ahead. Always tell somewhere exactly where you are going and when you will be back. Always carry highly detailed printed maps and never ever totally rely on computers, GPS and cell phones. Plan to save yourself.

I R Eagle Scout. Be Prepared!!

As I recall, you used to live in Nevada, right LaShawn?
Lots of open and remote spaces for sure. I did a lot of structural geology mapping around Silver Peak when I was a student.

Always good to go with a group, thoroughly research the trek and let people know where you are going.

Those open mine shafts can be a real danger to people who aren't desert-wise as well as some who are.

My wife grew up in a small town south of Reno and some of her high school classmates were out riding motorcycles cross-country one weekend. One young man was far behind the group and trying to catch up. He sped up, took what he thought was a short-cut, and rode right into an open mine shaft. It took several days to recover his body.

And yes, daytime and nighttime habits of poisonous reptiles differ. I was out in the desert one night years ago seeing what I could find with a portable UV lamp -- and that's how I learned that rattlesnakes (some at least) fluoresce! I found several around a mine dump that night, enjoying residual heat from the warm rocks. They'd all been shaded-up, staying cool and hidden during the heat of the day.

You just have to be aware of your surroundings is all.

If you see a tailing pile then you know that there is a shaft somewhere near by.

If you see ground that looks out of place with the other near by surroundings then open your eyes!!

Work the buddy system and just don't walk side by side or one in front of the other real close.

Space yourself out 10 feet apart as a safety measure.

It's not like you will get swallowed by an invisible black hole there will always be tell-tail signs.

Wear good boots above the ankle.

You'll be fine just keep your eyes open as to where you walk.

Very simple very straight forward.

Go out and explore and have fun!!

Wish I was there!!!

I love it out in the middle of nowhere!!!

I R Eagle Scout

I never get lost!!
I just temporarily readjust my probable location

As long as it's in a small town like Tucson. Those dang big cities can be far more dangerous than the desert any old day! The bad guys don't fluoresce. :wink: :lol:

My son found a similar specimen on a recent arrowhead hunting trip to Lyons county. He didn't show it to me until after we returned home in California so naturally I grilled him about the exact location he found it. My wife also found a fist sized Agate at the same location. We are heading back to the area in a couple of weeks to spend four days hunting arrowheads and minerals. I have hunted arrowheads and prospected for gold for a long time so I am very familiar with how and where to find both but this will be my first trip actually looking for gemstones. Any advice on how to look for the two minerals.
