To the White Forest
1) Freeman will be alone in the dark mines once he grabs a crowbar. He will pick up a shotgun, blast some acid ants, and come across a shallow pool populated by ant lion grubs, acid ants, and ant lions. A second pool will be deep enough for Freeman to diver under a submerged tunnel to reach the other side (and see a drowning ant lion). Before encountering Drowny the Ant Lion, the deep pool has an underwater web cache you can break using any attack.

2)You should have survived the Starship Poopers scene and have the Vortigaunt as your partner. The first room encountered past the shutter with acid ants has a web cache and is right at the entrance to it.
3) After going through the acid ant room past the shutter, the vortigaunt may something about acid ants and their rock spray; basically one cache is at the entrance of the room, the next one (this one described) is at its exit.
4) After the acid ant room past the shutter, there is a long tunnel leading to the man-made section of the mines. This cache is in the ceiling at the entrance of that long tunnel and unlike the cache at the exit, there is no live grenade from this cache.
5) After the acid ant room past the shutter, there is a long tunnel leading to the man-made section of the mines. This cache is in the ceiling at the exit of that long tunnel and unlike the cache at the entrance, drops a live grenade once the cache’s web is broken. You may also hear the vortigaunt say something about the acid ants being more aggressive because their grubs have been destroyed.
