I never dreamed this thread would make it to 400+ posts.
It now looks like it will have a rocky ending. Many thanks to all who posted here.
I am now hosting a Facebook group for my stories. Any Faceboook member should be able to view the group: RAY BROOKS IDAHO STORIES & MISADVENTURES.

I'll keep posting mineral hunting & mine exploring stories & photos there.
Best wishes, Ray Brooks aka Fritz.
My new mineral find of the spring. A nice 8" chunk of intergrown Actinolite crystals.

Actinolite crystals
Nice Fritz. What are the other minerals? Is that from a skarn?
Block of actinolite, from the Franciscan Complex, Marin County, CA.
I dug this out of the dirt in the backyard where I grew up – probably weighs 20 or 25 pounds. It’s tough not to become interested in geology when you’ve got this kind of metamorphic petrology in your blood.
The small, light-green specs are either phengite (a variety of muscovite), or clinochlore (a variety of chlorite) – I’m not exactly sure.
The small, white patches in the lower right of the second and third photo are, I believe, composed of fibrous tremolite.
Glaucophane quartz schist, from the Franciscan Complex, Marin County, CA.
Andalusite schist, from Northern Nevada. This variety of andalusite is called chiastolite.
Andalusite is one of the three Al2SiO5 polymorphs, along with kyanite and sillimanite.
Yosemite hippie-climbers refer to chiastolite crystals as “cross rocks” and were known to make necklaces with a series of the crystals.

Minerals! Nice photos & story!
Re your questions on my Actinolite. The other minerals are unidentified by me. Definately a skarn area. My buddy found a large chunk of actinolite with little spots of native copper & some chalcopyrite too.
Here's a 4" actinolite crystal I found. It is quite fiberous in surface texture & is dark green.
