I have trouble telling the difference between Topaz & Tourmaline. But if you go to Pala, afterwards go up to Palomar mountain and see the Observatory, and it's campground. It's awesome. There's also an old green fluorite mine up there, if you're into adventure. I say that because it's on the back side of Palomar mountain, you have go half way up a nasty dirt road (if it's still an open fire road) Then hike to the mine. If you're lucky, you'll find the only water fall on the mountain. I grew up on Palomar, it's a mini Yosemite. Every kid went to sixth grade camp up there, and I got into trouble for trying hike up to my uncles cabin.

As a kid I grew up in Quincy CA, and belonged to the rock club in Taylorsville.  Lot of mainly copper mines in that area.  We did find some tourmaline in the area around the Lassen/Plumas county line above Taylorsville/Genesee.  Been 50 years ago, and haven't been back up in that area since, so couldn't suggest a spot to look.  Was not gem quality, had some inclusions and fractures, but you could have made small earrings out of it if you were faceting, or pendants it you tumbled it. 

As I remember, what we found ran from dark geen to black.

My first stop would be the state minerals/geology dept., followed by some college/university geology/mineral dept. inquires.   That should turn up something in the archives somewhere.

I know what we found was up high, between Taylorsville and Antelope Reseviour.  Somewhere about halfway between what would be Taylorsville and the big copper mine with the tramway that was east of there....can't pull the name of it out of the brain at the moment.

I have claims northwest of antelope lake and there is tourmaline in that area as well as Thompson peak and in Lassen co. and north western washoe co. nv. but I think the big deposit is in plumas co. between quincy and junction with70 and 89 at the feather river down in the Spanish creek canyon.

There was a large travertine mine at the bridge that went down in the canyon and they used to haul it up on pallets to load the trucks. A friend of mine said there is tourmaline as well in the area. Tom

That mention of travertine triggered that there was another deposit of it 2-3 miles up 89 from the junction.  Might still have a piece of that in the remaining collection.  It was some pretty good looking banded material, and polished fairly decently.  There is also Ryolite up toward Mt Hough from Taylorsville.  Nice color, but fairly soft to try and do anything with.

Tom -  Since you have claims in the area, you might know of this one.....on the road around the south end of the lake, a spur road took off at about a 30-40* angle, headed SW off the main road.  IIRC it was somewhere about half way around the south end of the lake.  Not very far down that road was an obscure turn off that went west.  Just around the corner was the remains of an old cabin, and a small creek.   Across the creek was a mine adit and tailings, rail tracks on it for mine carts.  One cart in the mouth,  buried up to the top of the wheels in decomposed granite.  Below the adit was a big iron wheeled compressor, I'm guessing from the '20's.  We got the base of another cart from there at the time (around '67-68)  I still have the axles and wheels of that one.  Always wanted to get back and get the other cart.  We got a section of rail as well.  If you followed the road back beyond the mine, about a 1/4 mile was a nice wall of "devil's post piles".    But back out near the junction of the main road was an area of agate and jasper stones that were about the size of jellybeans.  Well washed and tumbled already, saying that that spot had some pretty good beach action  eons ago.  Mom and I named it "Jellybean Park", after the old Yogi Bear cartoons of the day.  You could fill a 3 lb coffee can in around 15 minutes.

You might also remember the smoky quartz crystal deposit over east of Beckwith and about 4 miles up 395 on the ridge east of the highway.  I know they finally closed it off many years ago.  Some ameythist crystals came out of there along with the smoky.  Some real nice ones back then.
