That was my first choice to as it did say they enetered south of the highway.
What threw me was the river to cross to get to Stout Grove, but I dont know if it's a big enough river you have to swim or just a creek.

That's what threw me.
Mario, can you get any decent detailed topo maps?
I like these puzzles ... sort of like those mystery orienteering hikes with compasses and a map.
Also, they didn't seem to concerned about taking a heep of gear for staying the night etc, just wearing a T-Shirt means (for "exploreres") they were expecting a day stroll and little chance of getting lost ... probably due to roads on boundaries.
Pity those other trees aren't marked, then it would be a lot easier to nail it.
Nice, just had a Google Earth update, some 13mb file, way clearer now!
Mario, I have orientated my map same as yours, noticed that from Stout Grove a track follows the river south to a bridge.
Also I carefully scanned that area looking for some daylight patches and circled likely ones in red but more likely ones in yellow.
That's the way I'd go in to have a look to save fighting the terrain.
