The rocky terrain acts as a sort of maze that branches to different areas. One path leads through the ground level of the room, starting at the Dynamo Chamber and eventually leading to a clearing with the door to the Trooper Security Station. Two Splinters will attack Samus as she passes through this route, and three Dark Troopers will attack in the clearing. These enemies will appear only on the first visit.
The upper portion of the room can only be accessed using the Space Jump Boots, and by extension the door to Storage Cavern A. A middle ledge has a small blast shield on the ground. It can be destroyed with a Morph Ball Bomb to reveal a Missile Expansion underneath. On later visits, a number of Splinter Cocoons and War Wasp Hives throughout the room will spawn a number of Splinters and War Wasps.

- "We'll be making our stand here. The engineer tells me there's no way we'll get the ship's engines online, and the atmospheric interference is scrambling our distress beacon. If anyone reads this, know that we did our duty and fought well." —Metroid Prime 2: Echoes Logbook "PFC L. Brouda" (Metroid Prime 2: Echoes)
