For those who are interested in poking around into possible locations where the Thomases could have stopped, climbed a hill and taken a 360 photo before stopping at Kelbaker/HH, here are some coordinates, with an estimate of how far away from Kelbaker/HH:
34.768525 -115.631748 This is about 300 feet from a trailhead, provides a turnaround for an RV. It's then about 3/4-3/4 of a mile to a granite outcropping that, IMO, would be very hard for most people to climb. 45 degree angle or less. Steep. Granite. Some darker rock. Lots of loose scree, most people trying it would be climbers. The ridge at the top would be about 2000' of elevation gain. Quite the strenuous hike.
34.722238 -115.677195 This is immediately adjacent to the freeway, not filled with lovely vegetation like the Granite Hills hike and the "scenery" would be the freeway.
**Neither of these has a parking lot up the road a ways, such that RT could have pointed to it. IMO
***Further south has no climbable hills, these are steep cliffs (volcanic I think, so slippery). Also it's hotter than anywhere else nearby and lots of black rock (not far from where the Schmeiers died). So, I don't think it's likely they stopped there.
If they got off on the 66, they'd be heading back east, not to Kelbaker and there are no obvious trails, trailheads or parking areas.
Goffs. If they wanted to drive up Old Route 66, and if they stopped to climb hills more than once, Goffs would be a place where it is possible.
Thing is, LE have to know their itinerary. There have been no calls for SAR personnel to go to Goffs (unless they did it top secret? Does that ever happen?) If RT turned his location services and his phone off, right before he got to Kelbaker (where he used it for a call), that's down right suspicious (so I don't think that happened).
Could LE be this slow at organizing the next search site? I think it's unlikely.
There's also the Camino Airstrip area. Maybe they stopped to check it out and climb the low hills nearby? You can google map that one. About half a mile from good parking at the airstrip to the hills - but of course, the airstrip would likely be visible in photos so as would a big stretch of the I-40.
So, I just don't see them pulling off and taking a different 360 picture that shows a completely different location than Kelbaker/HH and LE not calling in at least a few searchers for the stop immediately previous to where the 911 call was located.
It's simple - LE doesn't think the photos will help solve the case. Either they believe she got lost and fell victim to the elements or something nefarious happened or maybe something else that I haven't thought of but the photos and the public are of no help to them.
Except the public can be of help by assisting in the search. I believe LE has made that easy for the public to assist. May give another indication of what LE thinks happened.
I think there are only two possibilities. One of them is exactly as you say about the photos. They think they won't help solve it.
OR, LE already believes that the photos will be given into evidence in future. That showing them would convey something that could compromise either a trial or future investigation.
(Well, there could be a balance between the two I guess).
