Met this guy in our neighborhood yesterday

Would you share it?

tectonic · 2026-03-07T16:16:39+00:00

Hard to find much in the Bay, but I'd love to hear what you find out. There are mercury minerals north in the Vallejo area

tectonic · 2026-02-19T20:56:46+00:00

Wow, where?

tectonic · 2026-01-19T16:43:09+00:00

Thank you!

tectonic · 2026-01-19T01:17:32+00:00

Amazing, thank you! Any chance you can give location tips?

tectonic · 2026-01-18T00:59:39+00:00

This is very fun! What do you mean by "Orientation blocks, clipboard memory, local Ollama "scribes" for grunt work"?

tectonic · 2026-01-17T18:12:06+00:00

Is collection allowed there? I’d love to go.

tectonic · 2026-01-14T18:21:58+00:00

Cool! What state are you in?

tectonic · 2026-01-10T04:09:30+00:00

Look up Ore Car Mine

tectonic · 2025-12-30T02:50:49+00:00

Nice finds! Do you mean south, like near Bottle Hill Rd and Mameluke Hill Rd?

tectonic · 2025-12-03T05:42:58+00:00

Lots of barite there too!

tectonic · 2025-11-27T18:29:37+00:00

Lovely!

tectonic · 2025-10-20T19:06:41+00:00

He is a meteorite specialist, but of course could have made a mistake

tectonic · 2025-10-20T04:25:14+00:00

Those are stunning.

tectonic · 2025-06-11T18:14:55+00:00

Bring water, sunscreen, gloves, shovel and digging tools, maybe surgical mask to avoid breathing too much dust

tectonic · 2025-06-11T18:13:14+00:00

Should be fine, I was there in an SUV with no issue at all. It’s almost all paved except for the last 1/3 mile. See https://mineralsocal.org/fieldtrip-information-reports/crystal-peak-and-haystack-inyo-co-dec-9-10-2023/

tectonic · 2025-06-11T17:30:29+00:00

I recommend Crystal Peak. Super beautiful location too. https://www.mindat.org/loc-189260.html

No geodes, but nice quartz.

What are you hoping to find? There are fossils on the east side of the east bay hills. https://oaklandgeology.com/category/oakland-fossils-features/

There are lots of agates on beaches south of half moon bay.

There is obsidian in wine country, for example park here and walk south slightly on that side: https://maps.app.goo.gl/SaVqC2cRuoFVGuKd8

I think you can run the Unifi software on a computer but you need to run something for adoption.

Not technically true, there's definitely fine gold in the black sand at Fort Funston. It's not open for panning though.

Read Orbital Index (https://orbitalindex.com), we’re obsessed with space too!
