I agree but it really makes me wonder if there were so many visitors (which of course I don't doubt) why didn't anyone see him after the last sighting? I know he had quite a few things with him for camping did he have a filter so he could drink water if he ran out? I don't remember I will have to go back and look. If he got lost which of course is possible he would have water available at least. Some sign of him should have come up by now. This missing person case baffles me, especially if he had a water filter (which I don't know he did at this point or not) and the area being visited so much. ?????
People not being seen or remembered in Yosemite is...standard? What I was trying to say is that if every time a person is out of their car or on trail, they see about 100 people per half an hour - they aren't going to remember the individual characteristics of that person. On some trails, it's more like 300-500 per hour (but not in the area in question).
When I am in Yosemite, it's to look at nature, at the flora and fauna and to discern and learn even more. I ignore people as much as possible (and many others are of my ilk).
It's the fact that his stuff wasn't found that's a mystery. OTOH, if you leave things behind on the trail, a good number of current hikers in Yosemite might pick it up and not report it.
Doesn't matter if he didn't have a filter, a person in Yosemite who needs water will drink in the high country (and see a doctor later for giardia - if they are knowledgeable).
It's truly baffling, water filter or not. OTOH, there are quite a few people still missing in Yosemite (or the Sierra in general) and in many wilderness areas.
Visitors stick to the trails. After I became a WSer, I did notice one couple going off trail with big backpacks (they actually asked someone if they could get to Cathedral Peak off trail, we heard that). I never read about a missing couple, so after they set up (cross-country) I never thought a thing about it and other than being able to say they both had brown hair and he was at least 8 inches taller than her - and they had big dark colored backpacks and good shoes - I remember nothing about them (even though my DH immediately said that he was worried that they were young and going off trail).
Apparently, those two made it. If a person in Yosemite tried to memorize every single person, I'd want them to submit to a study about memory - because, I don't think most people do.
Anyway, baffling as heck. I don't know his equipment or actual planned route that well, but both human and non-human animals scavenge various kinds of equipment. People fall into steep terrain. There are people missing in most mountain rangers for these reasons.
