It says, both in the Dungeon magazine, and in the hardcover book that the Wall of Force is marked on the map. Well, it is not in either of them.
Can someone point to a map (online if possible) that shows where the Wall of Force is? Also, if it is there to prevent the geyser from spreading, how does someone get pushed into, or willingly enter the geyser?

I allways immagined the wall of force covers the eye socket, leaving only a geyser sized opening so that the plasma can stream out. In other words, nothing can enter the chamber through the socket, but plasma can exit it.
on other words, there's nothing protecting the geyser or anyone in the room at floor level.
