I've not seen this flagged on here yet - I was browsing google maps and discovered that someone has hiked cottonwood pass-> whitney with a 360 camera. It's not a full google trekker, looks more like a consumer 360 camera, but nonetheless it gives a really good impression of the trail with 360 photos every few hundred yards.

Don't know if the link below will work, if not just head for anywhere on the route and drag the little streetview man symbol onto the map.
