Serpentine Maps
I have put a lot of work into improving maps of exposed ultramafic (serpentine) rocks in California, Oregon, and Washington. Anyone who knows a local area is invited to help (you can just advise me - I will handle all the map generation).
One example is shown at https://docs.google.com/presentation/d/1vPJH04YXaf67UrBTdP6CD0AABA4Yw0mxWLhg96RFiI4/edit?usp=sharing

@jhorthos, it is my understanding that there are areas within Sierra Azul Open Space Preserve (near Los Gatos, CA) that are serpentine.
Thanks for all the work you're doing on this project!
@truthseqr I will take a look to see if I can figure it out. Thanks!
Yeah I have made some additions in that area and two regions are on the USGS maps. If you want me to send specifics let me know.
I'd be happy to help out with SLO county.
Hi Paul - that would be great! If you send me your regular email I can send images (or better yet KML files which are easy to load into Google Earth). - James
This open area is a tiny serpentine outcrop:

Cool - that spot lies just outside a USGS boundary so I just added a little bulge to cover it. That is exactly the kind of outcrop I can't do from sat maps. - James
This might be useful for Serpentine leads if you haven't already incorporated it:
