They've been missing since Monday. Dehydration and exposure, combined with poor wilderness survival skills, should be taking their toll right about now. Time is, unfortunately, running out.
This Gofundme was created by Justin Samenfeld, Jake Smith, and Briana Gonzales of Los Angeles, California to raise money for the search and rescue of Aaron Morganstein and Masha Mitkova. Aaron and Masha are two extraordinarily bright, family-oriented, loving individuals who come from WONDERFUL families. They are good-natured, honest, sweet, peaceful, highly intelligent, creative and genuine people who brighten up the lives of everyone around them.
People can survive for about 3-5 days without water. If they weren't travelling with water they are probably close to the upper bound of this. Its entirely credible.
True. But their car seemingly has not been located; that suggests they didn't stop at a well frequented trailhead.
One possible scenario is that they suffered a mechanical breakdown in a remote road or wash, similar to the Death Valley Germans. If they had, say, a 5 gal jug of water in their car (as one should, if headed into the desert), they could survive much longer if they remained with the car, did not eat, and did not exert themselves.
Priority obviously needs to be locating the car, which aerial searches are pretty good for.
