There aren't any "camps" right near this area. There is a ranger station (on fire road) relatively close. And given it is national parks week I would be surprised if someone would take her to a public area. Can you clarify camp? Are you talking about places for hikers to stop and spend the night? Or something else?
Two other women missing from this area were found off state route 3 in Lignum.
I would start asking the farmers, horseback trail riders, hunt clubs, and the like to keep an eye out for recently disturbed areas- and new tire tracks. Rain is headed this way by the end of the week. They need to find something soon.
My thoughts echo that of other posters- if she wasn't found this weekend, when the park would have been busy with good weather- she might not be there anymore at all.
Like homeless people or drifters camps. I never saw anything like that in the SNP. Assuming that she was attacked and taken, the attacker would have taken her to a car. If she parked in the remote Parking Lot (not the one close to Skyline Drive) then it would make more sense that the car she was taken in would be in the same parking lot. She could have been just left somewhere in the trail too.
Lets hope is none of the above.
