It's Pit Week here at the Nine and Thirty Kingdoms!
I've done the occasional pit in previous geomorphs, but these two F-series geomorphs focus on two pits, rather than on bridges, gears, or devices for crossing pits. F3 and F4 are nearly identical, with one small (10 foot diameter) pit completely blocking a tunnel and a second large one bisecting a cave. There are also two rooms and a small cave in both geomorphs. The difference between the two is that, in F4, there's an opening in the south end of the large pit that leads into a room with stairs leading up and out; in F3, the room in that location has a slightly different shape and doesn't have any stairs (everything is on the same level, unless you add your own stairs.)
Pits are a pretty common dungeon feature and can come in many varieties, but it seems a shame to drag out a series of pit-focused geomorphs over an entire month. It would be a little wearying after a while. So, I'm planning on doing a more pit geomorphs this week, to get them all out of the way.
Happy Pit Week, everyone!
