The Gully is a room in the Tallon Overworld in Metroid Prime. Samus travels through the room after using a "Half-pipe structure" in Tallon Canyon. It is a narrow room open at the top, with many Tallon ferns and other plants on the floor. A Glowing spidervine exists near the "ceiling". The rock walls, which are green with lichen or moss, are covered with luminescent objects in places.
