Special locations
From Halopedia, the Halo wiki
In Halo: Reach, some maps contain special locations that appear on the player's heads-up display when they reach certain areas:
Walkthrough
On Powerhouse, if the player drops down the waterfall to one spot on the rocks where he/she can't be killed by the barriers then the location next to the radar will say "Vaya con Dios!" which means "Go with God."
On Condemned, if the player manages to get out of the map, on the ouside there will be a small portion where the location reads "Space".
On High Noon, if the player go to the center of the map, in the "Construct of mordia", in the lowest part of the structure there will be a text saying "In memory of Peter Marks", who was the designer and creator of the original map, Hang 'em High, who died in 2009 because of cancer.
