Scotch Lake Quarry, Cape Breton Island, Nova Scotia
This is a very old place. The crystalline limestone that forms the bedrock is Precambrian, or over 540 million years old! The Scotch Lake Quarry was operated from circa 1900 to 1950 to supply dolomite, used as flux, at the Dominion Coal and Steel Corporation in Sydney. Problem is, all this other stuff got in the way.
The mottled greens to reds on the cliff face are serpentine.
That’s me in the picture. Mmmm, this one tastes like lead.
There’s material of every size and shape to suit your needs.
Don’t think you have to climb all the way up there to get it. The quarry floor is littered with easy pickings. In this photo alone I see dolomite (white), serpentine (lime green), pyroaurite (blue) and hematite (rust).
Laura and I were on a tight schedule, so we only spent about an hour collecting here. The tailgate photos are wet to bring out the wide range of colour. The serpentine is reported as being “yellow, yellow-green, olive-green, blue, red and brown with a variety of patterns producing banded, spotted, streaked and mottled effects”. I think we found most of the list.
I have seen beautiful cabs made with the serpentine from this quarry that are obviously produced using wheels and disks. Serpentine has a hardness of only 2.5. Does anyone know if soft material like this can be polished with rotary and/or vibratory tumblers? Any suggestions would be greatly appreciated.
Darryl: Great trip, I enjoyed all the posts so I thought I would comment her since this one had the prettiest rocks, LOL. OUr serpentine cabs pretty well, I would think if you tumbled it all together making sure there was nothing else harder in there you would be OK, but I am a tumbler flunkie, so what do I know! Glad you are having a nice summer! Amber

bhiatt: well tonight at 8pm is when the verdict goes public about the Michael Brown case in Ferguson, St Louis. Im curious to see what happens. National Guard is ready again. I hate to say it but I think it might get bad again for a while with the hood rats.

bhiatt: I live due east 20 miles from Ferguson but Im in honky tonk town. Not worried. There is some hit list,lol, and Collinsville, IL., the next town over was on the list. Cant remember the exact spot that was listed though.

Shotgunner: stay safe Brad, stay safe. They shoulda announced yesterday during NFL while it was pouring rain. Scheduling the announcement so far in advance seem to invite bad actors.
Nov 24, 2014 19:05:30 GMT -5
bhiatt: yep. I agree Shotgunner. Now the crowd is gathering on the main street in Ferguson. Gonna last all night. TV is all local news covering it live. Better not cut into my Two Broke Girls lol. kidding

Shotgunner: In Florida arsonists may be shot and killed, not much pillage there. Missouri should consider taking Florida's lead.

bhiatt: yeah they were trying to keep from that happening. Not one shot was fired by police or the national guard last night. Tonight may be different. The news was reporting seeing lots of guns in the crowd. I guess they think even more rioting if the cops start

bhiatt: shooting back. There were hundreds of gun fire shots last night in Ferguson. 21 fires.
Nov 25, 2014 17:47:07 GMT -5
bhiatt: hundreds of nation guard for tonight. Them ghetto boys creep around in the shadows. Its hard for them to catch them. They throw them fire bomb bottles and run of and the building goes up in flame quick.
Nov 25, 2014 17:49:42 GMT -5
bhiatt: 2200 national guard, 700 police officers. Ew Raw! I shure hope they shut them pant sangers down tonight.
