Blast Furnace Observation is a room in the Pyrosphere in Metroid: Other M. The room is a facility suspended over a pool of Lava. A small hatch in the floor leads to an underground chamber with a Morph Ball tunnel. This tunnel is suspended over the lava and features several Grapple Points in the way which Samus must Bomb to release. One of the grapple points is swallowed by the Vorash, which Samus then battles and kills. In the arena where Vorash is fought, several rocks coming out of the lava serve as platforms, and mechanisms can be seen around the room, dumping trash from other sectors to be incinerated.
