I hope you are right but it seems like this is anything but a lost/accident case. - left her phone in California - made no safety plan Those both really point to intent, IMO. I think if she indeed just planned to do a 3 hour hike, she wouldn’t have a huge pack, she would have been seen by multiple people and would have been found by now. At this point the best case scenario is she wanted to disappear, that she had arranged for someone to meet her and transport her from that location. This would at least mean she’s alive.
