Samus travels through the room after using a "half-pipe structure" in the 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 are covered with lichen, green moss and other luminescent objects.
The room serves to allow Samus to reach the upper ledges of the Landing Site that contain the entrance to the Alcove containing the Space Jump Boots. It can be visited earlier in the game (in the original NTSC version of Prime) if the Bomb Space Jump technique is used.
