The Phendrana Canyon is a room in the Phendrana Drifts. The room is accessed from the Canyon Entryway. There are two platforms at the entrance, one above the other. The lower one has a number of crates and a Chozo Lore entry. The main part of the canyon is a giant Half Pipe. There is a walkway on either side, but only the right one can be accessed from the ground. Crystallites can be found on both walkways, while Baby Sheegoths can be found in the bottom of the canyon. The right walkway leads to a number of floating platforms that are not able to be navigated in their original position. These platforms lead to the Boost Ball. A nearby Scan Terminal will move the platforms into an easily climbed position. The platforms will crumble away shortly after being stepped on, so Samus must move quickly. If she falls the platforms can be reset using the scan terminal.
