Title: Obsidian
Post by: yukonjade on September 29, 2016, 08:43:25 PM

   I took a ride the other day and visited the Newberry national volcanic monument
 near my home Bend Oregon and took a few pictures.They are of a solid obsidian flow,to get an idea of the
 gigantic area it covers Google the monument.

We have something like that a few hours from here. Obsidian Dome, part of the The Mono–Inyo Craters. Formed recently, 5000 to 500 years ago. Much of it is full of pumice but some spots have some very nice mahogany, rainbow, and other kinds. Our club is going there on Oct. 22nd.

I visited there a few years ago! Had a great afternoon walking the trails through the lava flow. Amazing place.

Yes, Newberry is a great visit for anyone interested in volcanos. It's Oregon's other crater lake, with 2 lakes in there. No collecting from that obsidian flow, I think it's still the world's largest (collecting hasn't been allowed for several decades). Some great lava tube caves and a waterfall to visit within the monument. Still an active volcano & you can go to certain places along the lake shores, dig a small hollow and let fill with water and it heats right up for your own personal hot spring. Thanks for the pics - it has been too long since I drove up there.

I visited Newberry some ten years ago. Certainly an impressive amount of obsidian and of different varieties. Was soooo tempted to put a beautiful and large rainbow boulder in my backpack but in the end honored to no collecting signs.

Cheers

I just returned from Glass Butte, OR.  PLENTY there that you can collect.  We had a lot of fun wandering around. the site is probably 20-40 square miles.  Found gold sheen, silver sheen, plenty of mahogany in every form, and a bit of fire and some rainbow obsidian as well.  The rainbow is not SUPER vivid colors, but still interesting.  We met some folks there that told us about one locality at the Glass Butte site that had some gold sheen that was in the form of tiny circles (he showed us a very small piece), but despite his directions I could not locate any of the gold 'spot' sheen obsidian.
