As we look forward to progress, meeting new people, sharing new ideas and rock sharing.

Obsidian is a fun theme if your looking for something to bring for our sharing time / show & tell. Naturally we have a lot of it in this state and other than just beautiful black it gained alot of variation to it as it cooled rapidly from Rhyolitic Lava. It is a rock that did not have time to form crystals (so really did not have time to become a rock but just glass). It also has very low water content in it’s make up, which affects it over millions of years. It has had such a major impact to early humans so it is very historically significant.

Well I think the variations are just amazing and it’s also fascinating to think that we are the only place and state that fire obsidian has been found. Below is a photo of my show and tell a new find of obsidian from Mexico called Starry Night Obsidian, purchased at the Portland Regional Gem and Mineral Show last year. (so keep checking on those shows for new finds).

These meetings will continue both on-line through zoom and in person simultaneously for the first meeting of the month.
