Geothermal Caverns - Guarded Tunnel with Base Camp - Part 3

Alternatively, if you just wait up on the dark ledge, the 3 men will eventually open the gate below and wander down to the pit.

Like the peeing guy's friend, once they reach the pit, they vanish, although they sometimes leave their flashlights behind. Once they're gone, you can continue your explorations, but you won't get the XP and salvage from killing them.

When the coast is clear, burn the sack (4/6) hanging near the gate for the Firestarter Challenge. (Even if you explode the gas vent, this cocoon miraculously survives the blast.)

Open the food cache on the wooden ledge near where you climbed up from the other room. Then drop down and loot the bodies.

At the north end of this cave is another food cache and, lying next to it, a GPS cache (4/6).

Hanging above is another sack (5/6) that you can destroy with a fire arrow for the Firestarter Challenge. The nearby doorway leads nowhere.

So climb the ledges on the left side of the room to reach a rough climbing wall.

At the base of this wall is one of those succulent persimmon plants, or whatever they are. Chow down...

...and then head for the top.
