Geomorph #76

Somehow, the topic of underwater submarine bases came up at work. My blogger's ear perked up and I immediately tried to imagine a submarine base as a dungeon geomorph. Like Geomorph #60, this one has more than a touch of weird science. The alien or relic submarine is tied up to a wooden dock in the middle of a subterranean lake. Deep below the surface, there is certainly submersed tunnel that leads to the sea (and possibly other lakes within the dungeon).
