Quarantine Zone: Leave level boundary

[SmokiestGrunl]

Note: This trick requires the Sputnik Mode Skull. When you get off the ledge that it was on, walk about five yards in front of you then turn right. Walk to the rock face that is in front of you, on the right of the stone wall. When you have found the rock face, find the least highest point in it. Then, grenade jump directly in front of it. If done correctly, this will blast you on top of it. You will now be able to walk on the mountains on the top of the level. If you want to get past the level boundary, just walk forward and follow the ledge until a steep hill is directly in front of you. You can walk up this hill and will be on the edge of the level. If you keep walking forward, you will be able to walk in nothingness past where the ground stopped.
