'''Rusty Mountain''' (Japanese: '''てつさび{{tt|山|やま}}''' ''Rust Mountain'') is a playable dungeon the {{player}} goes through in [[Pokémon Mystery Dungeon: Gates to Infinity]]. It has 25 floors and no boss. This dungeon is accessible after completing the main storyline and is one of three dungeons where the player has a chance to encounter {{p|Thundurus}} through wandering with high [[mysteriosity]]. The fifth, 10th, and 15th floors have a golden locked door surrounded by a poisonous cloud that all require a {{t|Poison}} or {{type|Steel}} Pokémon and 2,000 Poké to pass through. The final floor is a two-roomed chamber containing a [[Treasure Box|Deluxe Box]] and valuable items such as rare [[List of TM and HM locations (Mystery Dungeon)#Gates_to_Infinity|TMs]], and [[Device|Devices]] of the same type as the enemy Pokémon encountered in the dungeon. [[Weather#Weather in Pokémon Mystery Dungeon|Hail]] and [[Weather#Weather in Pokémon Mystery Dungeon|Sunny]] weather are both likely in this dungeon.
