An East Bay wall crosses Tomales Point, in the Point Reyes National Recreation Area. It's faintly visible on Google Earth. I took some photos, uploaded them to Panoramio, tagged the location. They can also be seen on Google Earth 38°12'20.32"N 122°57'57.67"W More information about the Tomales Point Wall can be found here: http://www.tamdistrict.org/drake/science/stones This page also documents that the wall was already present in 1862, and already appeared old at that time.

perhaps built by the Spanish? cattle rancheros, etc. 2602:304:CDAF:A3D0:E9F6:A7E5:A44C:7468 (talk) 17:13, 10 May 2015 (UTC)Reply

I have read that similar walls can be found in plain sight over large portions of California

Here's one example: http://www.messagetoeagle.com/mountshastamegaliths.php#.UocMDKWoVuY 108.219.39.17 (talk) 06:12, 16 November 2013 (UTC)Reply

Yes indeedy. More;
http://www.newser.com/story/230029/the-east-bay-walls-continue-to-confound.html
Now, local archaeologist Jeffrey Fentress is measuring and mapping them so as to gain them entry into the state archive, which would lend protection from things like development.
I'll bet this Fentress guy will be the authority soon: http://nagpra.sfsu.edu/page/contact

Added more info and references

...to this article. Removed the multiple-issues tag that had been placed on it. Thanks for links, folks, they were helpful. Someone could probably use more of the info in the various articles, and find even more now, as interest seems to have been piqued in the Bay Area recently.

I'm still looking for the article--thought it was in the SJ Mercury News--saying that they're generally not saying where the walls are, to protect them from idiots. Er, I mean, vandals and souvenir-seekers. Elf | Talk 23:13, 17 September 2016 (UTC)Reply

HEY, these rock walls may just appear in other parts of California. Wait, they do!

In the section of what is truly "Northern California" in multiple locations between Weed and Yreka alone, this same type of rock wall condition can be seen for miles over the landscape. Even just off of I-5 they are readily noticeable. Here is just one for instance.
