This week's mini-map is the Icy Crevasse (16x11), another snowy one for you. This one is a small, frozen cave, or maybe a crack in the ice that your players have fallen down into, fortunately landing here onto this level instead of falling even further.
I tried to draw the two exits of the cave to look a little ambiguous as to whether they're actual exits or just terminate off screen, so hopefully you won't feel like you have to build off of this one in either direction if you don't want to. That said, there's definitely an area down below, so you'll have to have an answer for what's down there when your players start poking around.
