Tallon Canyon is a room in the Tallon Overworld in Metroid Prime. It is a large room containing several waterfalls, a pool with Blastcaps, two Great Trees and a number of ledges around it to climb up, and a Half-pipe. The half-pipe can be used with the Boost Ball to reach the high up natural bridge in the room. This leads to a low opening block by a series of Sandstone walls that can be destroyed with Bombs.
