I've finished my second Water Geomorph for the +GeomorphMapContest. It's called The Fishbowl.
"Years ago the Dwarves discovered this natural cavern while mining, and found that it was plentiful with fish. Now the Dwarves are gone, and goblins live in the once splendid Dwarvern Halls. The goblins don't fish in the cave's waters though. Something terrible now lurks under the water. Long, suckered tentacles lie coiled beneath the surface, ready to snatch anything that dares to cross the bridge above. The goblins use the bridge as a test to initiate young warriors. Arrows are fired across the bridge and the goblins dash across to retrieve them to earn their places as warriors of the tribe."
I might do a full write-up of this one too.
