Once more Down into the Dungeon, today's geomorph is based on the following image:
Specifically, it's based on a subsection in the center-left. There is a stair coming down into a hall of arches (some of them featuring sinister eyes lurking in the shadows). In the west, there is an exit that eventually leads down a curving stair to a pit trap splitting an east-west passage. Below the pit trap is water lair of some kind of creature that demands a virgin sacrifice at the pillar in the southeast.
