If you need further evidence that these pilots weren't really situationally aware, and never really had a clear mental picture of their location, consider this. If they were where they supposedly thought they were, one of their orbits would have taken them very close to Mt Bird. A pilot flying VFR who knew precisely where he was would have identified this. "Need to maintain clearance of Mt Bird/ no current visual on Mt Bird" etc. etc. But no reference to Mt. Bird was ever made.
