I agree with you on disposal sites. There are lots of pockets of desert close to Nancy's home that could conceal a body--areas along through roads without foot traffic or culverts, for instance. Your mention of Mt Lemmon seems plausible. You prompted me to share my early theory that Nancy could have been taken into the Pusch Ridge Wilderness Area / Mt Lemmon. It's close by. It can be accessed from nearby neighborhoods, trailheads, and roads that traverse it. Once off a trail or road, the dense vegetation and rocks in the flat, wide open areas or the crags in the rock faces could conceal a body or evidence. Air searches might have eliminated the flat areas near roads and trails. The outcrops in the lower rocky cliffs would make detection from the air difficult.
Given Nancy's physical limitation, It's not plausible that she was forced to walk away from her house or into the wilderness as Elizabeth Smart was. Posts here largely dismissed the idea of Nancy being taken from her home by off-road vehicle. Most ORVs are loud, they pointed out. Someone trying to be stealthy wouldn't use one on the roads in the neighborhood or to go through the open spaces behind homes. The noise an off-road vehicle is only a concern near houses. Once out of NG's neighborhood, the kidnapper could have transferred to an ORV and continued on.
After the video from the front door was released, I read an opinion elsewhere from someone familiar with the desert saying the kidnapper could be itinerant or camping. Based on his experience and the equipment he uses on off-road adventures, he thought the backpack looked like it contained a Starlink Mini. Initially, hiding out in the wilderness waiting for ransom seemed possible if unlikely. Even if that was the original plan, I fear too much time has passed. She's not alive, and the kidnapper is long gone. I think it is more than likely that a kidnapper would take an elderly victim into the wilderness area only as a disposal site.
The area outside of the neighborhoods is isolated and remote. There are plenty of places for a prepared kidnapper to hold a hostage or dispose of a body. I agree with previous opinions that well-intentioned untrained searchers going on unfocused searches would not be helpful. The area is too vast and unforgiving.
