West Furnace Access is a room in the Chozo Ruins in Metroid Prime. It is a curved, round metal tunnel that contains no creatures or other features of interest; it is only a room that connects two others.
A glitch can happen in this room in the original NTSC version of Metroid Prime, as it uses the original, faster loader. The game may crash while it is is loading the Furnace. This bug can be avoided by using a Wii.
