Just curious, where did you get the obsidian? We have mountains of it here in Oregon.

.........from one of those mountains... Or maybe they are supposed to be called 'buttes'

Yeah, there is Glass Butte, and Newport Crater to name a couple. I don't get around well enough anymore to be able to go over there and collect, but I used to camp at a spring on Wagontire mountain. Glass Butte isn't very far from there in a straight line, and there is obsidian there also, which I think was blown out of Glass Butte. Fifteen thousand years ago that wasn't a desert, it was a lake, and apparently the obsidian landed in water and cooled rapidly, because there are softball sized and larger chunks out on the flats, and the surrounding area. Sometimes many miles out in the surrounding area. I'm not a geologist, and have been corrected on some of my assumptions, but I think obsidian comes in grades, just like in different colors. The stuff on Wagontire mountain isn't near as pretty as that on Glass Butte, it's a dense black, and I don't have the words to describe it, but it flakes like obsidian, just not as pretty.

Maybe that is the grey stuff called Dacite? Sometimes called basalt too... Dull bland material really...

Hope the spot yields as good as it looks.

Probably 10 years ago, a winter camp on Glass Butte, Oregon high dessert. Snowed on us that night.



Glass Butte, between Bend and Burns, Oregon. On the other side of the left hand peak, up near the top, there is a flow of red obsidian. Lots of black obsidian on the mountain.



That's a regular shovel, note the thickness of the obsidian flow.



The shinny rocks are all obsidian, some red, some black, all mixed together.


Here is a closer look at the chunks of obsidian on Glass Butte. The entire mountain isn't like this, the overburden has been washed off over the years, it's just in some areas that the obsidian is exposed like this.

The next two pictures I didn't take, these are a couple of the obsidian flows at Newberry Crater.

This part of the field has yielded a few buckles and buttons . The part of the field to the west that you can't see in the picture has given me 6 LCs, a FE and 2 crotal bells this year . But the third cutting has not been taken off so I am relegated to the wheat field for now .
