I’d like to note that the official SOTA summit is the West Peak, not the (easy to access) East Peak with the road and fire lookout.
As far as I can tell, everyone has activated the wrong peak so far. I think that there are places to get into the AZ on the West Peak without going into the closed areas, but I haven’t had a chance to go check it out myself. I marked some areas on this map: SOTA Mt Tam Activation Zone - CalTopo
I think a case could be made that the East Peak is higher (it looks higher from nearby peaks), but that’s not what shows in the SOTA database.
