It's fairly easy to lose someone in our forests, and our vegetation is MUCH less dense than yours.
Someone who keeps their head and has some knowledge of the mountains can generally walk out of any area here within 24 hours. The creeks are like roads. Follow them downstream and you'll hit a trail or road someplace along the way likely that day. But if you're not certain stay put. Also if you're staying put stay far enough away from streams so you can hear. I can take you into an area where you could walk in circles for days though. It's an area called Catossa. No pattern to the ridges whatsoever.
