The only thing important is in the Ravine. The surface camp doesn't have much aside from the loot dropped from the bandits and some supplies. The good stuff is down below. Though you will need to act fast: The person down there will only attempt to fight if backed into a corner, otherwise he's going to make a run for it. Spend too long bickering about loot and I will take that opportunity to make him flee, taking evidence with him.
