Thu Nov 08, 2033 Tar and oil have collected over long eons and hang down in snaking columns from the metal walls of this cavernous room. The walls seem to be of different texture from the ones in the tunnels, the metal less refined and duller. The dimensions are quite respectable as its biggest dimension wanders around 100 yards and the smallest 60. To the south end of the cave, you make out some movement at about ground level, but hearing the strange rushing noise, your sensors determine that it's probably an underground channel of liquid of sorts. The only other opening besides the one out is located at the southwest end of the chamber. It's nothing more than an opening, and if you have any olfactive means you can make out something: IT STINKS!
