I guess Indiana morphed from the West Coast of North America (the present location of the Northern Cordilleran Volcanic Province - British Columbia, Yukon, Alaska) to its present location sometime in the 60s. It also bleached the black and red/brown colors out of the Obsidian on the trip eastward. Bob

Shelbeeray lives really close to the Tseax River Cone, if this green glass obsidian occurs naturally up there, maybe she has seen some of it? it is going to be a while before I get up there again....

i gonna be serious now ;D...earthdog if she found that in the sixties...please let her know that very high concentrations of lead and arsenic were used in glass at that time....and the slag contains way more than the actual glass produced. i was told by an engineer from olin chemical corp....not to cut ours...or even handle it much...because it still had the matrix from the pot attached to it....not really matrix....but the impurities that got seperated from the glass. the glass industry consumed 4,100 tons of arsenic in1968....3000 tons in 1971.....so 1 could assume...say in 1960....it was probably 10,000 tons...if not more...before anyone started watching out for the stuff. i ment to mention about the arsenic and lead when yaw were doing the slag glass.....but i forgot...sorry about that. dont know if this link helps or hurts any....maybe ya wanna read it...and maybe pass it on....kev. www.mindat.org/mesg-55-48054.html

Okay. I just spent 1/2 an hour typing a response, citing sources, etc. and then closed the wrong freaking tab and lost it all. So, here's the short version.
From what I know, and according to what my friends who are geologists, miners, assayers, etc. - Not a chance in hades that that is green lava glass or that it originated in or near the Nass valley or the T'seax flows.
I'd refer folks interested in the geology of the cordilleran range, our accreted terraines, etc. to the gov't of bc sites and to a book - "Geology of the Norhtwest Mainland" by Allen Gottesfeld, published by the Kitimat Centennial Museum Association (1985) ISBN 0-9691390-1-2 Another authority on the area, is Eileen Van der Flier-Keller (in an unrelated tangent - check out her little laminated guide, "A field guide to the identification of Pebbles" ISBN-10: 1-55017-395-2 - it is the COOLEST rock ID guide I have ever found and it's LAMINATED, fold-out brochure. TOO FREAKING COOL.
Could be a foreign implant. Nope, there is absolutely no manufacturing, etc. anywhere near the T'seax flow. She's correct in that. Could be melted glass of some odd origin. The only thing it has in relation to our region is that it is the colour of some of the water due to glacial clays.
If it ever proves to originate in the area, well, Elvis will be getting interviewed on Oprah.

This reminds me of a time I was in Ackley's rock shop in Colorado Springs. A lady came in with big piece of blue glass slag that she found in a local creek. She swore it was Aquamarine that had tumbled down from mount Antero (about a two hour drive west of Colorado Springs), it even had an inclusion that looked like a bug. Rhonda the manager has a good eye for minerals took on look and said sorry it was slag glass. The woman was adamant and challenged Rhonda to identify the inclusion. Rhonda got out a loupe and said it looked like a piece of dirt. The woman was incensed and asked where she could get a more expert opinion on it. Rhonda sent her to a nearby jewelry store that was owned by a GIA certified Graduate Gemologist (GG). I had to excuse myself to the restroom because I was about to pee my pants from holding back laughter.
The lady left to go get a more expert opinion from the GG. Rhonda later filled me in on the rest of the story. The GG called Rhonda to thank her for referring the Aquamarine lady to him. He was laughing so hard he could hardly talk. He told the woman the same thing. He even tested it for hardness and it tested the same as glass. He couldn't do a refractor or spectrometer test because the piece of glass was too big and she would not allow him to break of a chunk of her precious gem. The lady was not impressed and wanted a more expert opinion. He referred her to the Denver Museum of Natural History mineral dept. or the Colorado School of Mines in Golden.
I wonder who they sent the lady to when she didn't like their opinion?

ok!--- I had to think about this for a couple days ! ---bear with me for a minute ! ;D ;D ---- about a month ago either the travel channel or history channel had a film on about the "green Glass" that is in the Sahara desert --- I've watched that film a couple times before so didn't watch it this time --------- but they do find green glass (obsidian) over there that they say was from a metor/comet that hit millions of years ago --it exploded in the air so left no crater but the temps were hot enough to melt the sand into green glass -- when I first saw this film I wondered how I could get a piece --- guess I could just email "her" ?---- bet she watched it too ;D ;D another glass making machine ---was the old steam engine trains --- they would line the bottom of the boilers with sand to build the fire on to heat the water to steam -- it would sometimes get hot enough to melt the sand and form glass -- they would break it out and dump it along the rail beds -- some of which you can find today along some of the old rail lines --could also of come from there But I'd say it was just plain glass too! ;D if you want to call it obsidian tho, I'll let you ( P. S. -- I have some colored obsidian that I would sell too ! ;D )

Hmmmm. Looks like it could be Fulgerite. I'm just kidding, I have not a clue, but I have enjoyed reading all this! I learned a lot, thanks to all! And I really enjoyed all the pictures. I'm looking forward to the Elvis on Oprah hour!

Interesting chunk realrockhound Kind of a Camo green. Reminds me of being about 10 years old and wanting to take home just a small piece of a giant chunk of obsidian that was yard rock at my grandpas place. I hunted around and found a tool, aka another rock. It didn’t take very long to learn that obsidian is pretty much glass and it’ll cut you right quick. And of course I had to hide that from everyone cause I wasn’t about to tell them I was trying to steal rocks! You know something else, there was a Randy there too. Definitely not as cute as yours though.🐶 I look forward to the next post on this thread in 2-5 years.🤓

I’ve heard someone has a claim on it now, but I don’t see a whole lot of it in circulation. I like your story. The funny things we did as kids.
