Mario, here's a google earth of the region.
Marked in yellow is where they came out, Stout grove, they got a lift to their car and went to a burger joint to pig out back in Crescent.
I divided the area into 3 regions, I did this based on rivers they didn't mention crossing (although they mentioned creeks). Personally I think they were in Area 2 as it's more mountainous.
The southern end of region 2 seems to have lots of tracks and trails which they never had. Also they mentioned entry from the road where they parked the car was no trails so I think they were in the RH part of Area 2.
I cant get any good topo maps online. Also that area has the odd clearing which fits in with the story.
There is a road running along that river on the RH side of area 2, my hunch is they parked there.
I don't know if they had a compass or not and why if that's the case they didn't go back the way they came or were a little lost following out creeks etc in another direction.
The whole park is not that big at 10,000 acres however it mentions everywhere about being thick with vegetation and inaccessible. So travelling a mile in a couple of hours is a big deal.
Really need a topo map to see trails and creeks and nail the spot, maybe there's some aerials of the area too, I'm sure though with 300' trees what all these maps show ain't what it's like on the forest floor.
