it is thick, dense, vegetation. and the terrain is extremely steep. some ridges still dotted with snow. one of the first things you notice, a good, 20, 25 degrees cooler at this elevation. it can get pretty cold at night. that's just one of the challenges autumn faced. another challenge was just figuring out where to go. well it turns out that perhaps the smartest decision she made was to follow the water. she follows it downstream. and that's eventually led her to a hiking path and that path led to a highway where she was picked up by those good samaritans. the plane en route from montana to autumn's home state of washington crashed on saturday afternoon. she was with her step-grandparents, leland and sharon bowman. according to authorities she tried to save them. did she tell you how she tried to save them? >> she had reached in trying to grab in and pull them out.
