Thinking about a trip to the Davis Creek area north of Alturas CA to try to get a load of obsidian; maybe with a shot at Glass Butte OR. Already going to be in the Redding CA area for a few days around June 21.

Any tips on how to recognize the goods in the field?

Thanks.

All of the black obsidian we found near June Lake was on the surface and shining black, easy to spot...

June Lake is where?

East side of the Sierra Nevada Mtns, near the middle of the state, just off of CA Hwy 395...

The last naping class i took wasn't very good either. All we did was sleep.

Second class went much better. Even though I heard the same instructions, I knew not to follow them literally.

I learned more by watching what was done by the instructor and others, and from remembering what I saw on YouTube. Several participants used techniques they learned from different instructors, some completely the opposite of what was suggested.

I now appreciate these classes as just an introduction to an activity which is open to considerable experimentation and divergence of technique.
