Text, 900 pixel jpg, and the zip file for the Atlas. Larger jpg in my gallery.

1 three broken tables as a barricade. Debris with one skeleton under it.

2 looks like a last stand defense, so why is the chest not opened ?

3 west door is secret. south and east doors are wood and easily opened. Guiding away from the secret door ? A large green crayfish statue. Does it answer questions ? A pile of skulls behind broken barricades.

4 a pit. A fire pit but it doesn't look used. A spiked barricade, easily moved out of the way. Or should it be touched/moved ?southeast corner of the odd-shaped room on the west side does hang over the lava. it is either buttressed up, or it has no support and anyone walking to that corner will very likely break through and fall into the lava.

5 Two wood debris piles. Two skeletons. Two small trenches, they look hurridly dug. No tools here.

6 stairs down. Three large empty barrels. Open doorway leads to room 11. Corridors allow any being in room 11 to circle around behind the adventurers.

7 circular room. Note the small bit of lava at the bottom of the water. A statue with a bowl of greenish water. The statue could be gold, or fake gold.

8 debris. Did it just move ?

8A stairs up

8B a pit protecting 2 closed chests.

8C debris. Water leaking from the pile.

9 dead end, a trap. Fake door.

10 behind 2 secret doors and passageways. The level's big treasure could be in here.

11 Wood spikes as a barricade, they look new. Three skeletons. Three small bags, unopened. A metal spiked barricade that doesn't go all the way across the room.

12 stone bridge crosses over to a small anteroom room 13.

13 small anteroom to room 14 A skeleton. Looks like they might have been fleeing towards room 5 ?

14 a small corridor shaped room to room 5. A skeleton. Looks like they might have been fleeing towards room 5 ?

15 The Island. Looks like a stone wall or room was there once.

I think I have all in the correct order, just need to add some debris, et al, and type up the text.

first text, likely modified later.

I used partial names from the second generator. Added more names, etc. The yellow field is fallow.

I have seen geology programs and there are instances of ice caves deep in mountains. Not in the tropics though.
