A new tab was added to reflect current iNaturalist observation data and the deobscured data provided by project members.
Table is hosted by Google at https://docs.google.com/spreadsheets/d/1bXE0qFrbRfWxGI9lbkYH9y8ZJhuCBQZw04rt3mLBc64/edit#gid=919135906
Most project members will probably know all this stuff, but for those who don't or who stumble on the project, here is a guide to recognizing serpentine on hikes.

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
Already considerable improvement thanks to member data!

I checked a project download today more carefully and either the download bug is fixed or it is inconsistent, because this round the obscured coordinates for project participants are definitely available to me.
Thanks so much participants! If you know of other interested observers get them to join!
I tried my first download of location data with obscured location removed (one test taxon) and it worked as expected. Thanks so much for all of your help!
Hmm well I thought it was working but I used a taxon that had both obscured and normal locations and got back only the normal ones, so apparently there is a system bug. Thanks user efmer for pointing this out.
(note - only the admin can get the unobscured locations)
I have completed the initial list of taxa of interest, a mixture of known serpentine endemics and species that probably have some serpentine tolerance (part of the goal of the project is to test that). If you have any additional taxa that you think should be added, please let me know. In particular, I have probably missed many very rare ones.
I am currently adding taxa to the list for inclusion in this collection project. I hope to have upwards of 300 taxa eventually included, based mostly on correlation of iNaturalist observations and USGS ultramafic rock maps.
One of my purposes is to encourage observers to "trust" the project so that I can get access to unobscured coordinates for endangered taxa without risk to the plants, which I love (and will never release such locations in any way). This is important especially in California, where a substantial fraction of serpentine-tolerant taxa are highly restricted endemics with obscured locations, which makes it impossible to get quantitative information on their exact relationship to serpentine soils.
