Yes, I'd think so too. I'm just a little confused about where this is going. Do you think she's in the Lava Tubes? MOO
I think people are trying to point out that there are features that could hide a body.
I think it would be very hard to murder someone at the lava tubes (there are more people there than at some random spot in the desert) so a kidnapper wouldn't choose such a place. It would be hard to carry an already dead person to the tubes.
The perfect murder out that way would be made to look like someone died of heat stroke, although if one was interested in making something look like an abduction, the tubes would work because really, wouldn't it take two people to transport even a lightweight person from the parking lot to the tubes - quickly?
Amboy Crater would look good as a dumping spot as well. Not far from Kelbaker/HH. If I were someone who was trying to make a murder look like an abduction, Amboy Crater area would come to mind (road is usually deserted, can see someone coming, lots of places to hide body, could claim a southbound car picked up the deceased and placed her there, parking big enough for almost any vehicle).
There's a road with a defunct airstrip-like thing where a truck and trailer could park on the non-touristed side of the crater, and the rocks out there are like a maze and, while really barren, also sort of like a frozen sea of rock with tons of dips and gullies.
And a trail...a trail leading right into that maze of rocks.
ETA: part of my point is that a body could be almost anywhere out there...so it's really hard for LE to find one, without some clues...I sure hope there are digital footprints.
