Grand Canyon

Due to uranium demand shortly before The War, the U.S. government removed the Grand Canyon's status as a national park and allowed private mining companies to exploit its supply of uranium. The resulting mess was an environmental disaster. As a result, the Canyon has become one of the deadliest places in the wasteland, home to hideous mutants seen nowhere else. Sane people avoid it.

The player was supposed to enter the canyon to locate the remains of the second B.O.M.B. orbital station. On the way, he'd encounter a handful of characters, including scavengers and Victor Presper's soldiers.

Given Grand Canyon's size, transportation over to the other side is difficult. As such, before the war, a sky tram was constructed allowing safe passage over to the other side. However, after the war, most of the mechanism was scavenged - the player would then have the opportunity to locate the lost machinery (irreplaceable after the war) and restore the tram to full functionality.

North Lodge/South Campsite/Tram
Basically, a non-functioning tram bridges the gap between these two locations at the top of the Canyon. Getting the tram working enables a shortcut for trade routes. At the South Campsite is the Camper, the trailer attachment which can serve as a portable science lab.

Canyon Floor
Ruins inhabited by mutant creatures. The Grand Canyon was stripped of its protected status by the US government and opened up for uranium mining. The mining companies weren't environmentally friendly and the floor is littered with broken machinery and industrial waste.

Crashed B.O.M.B. satellite
One of the B.O.M.B. satellites eventually fell out of orbit and crashed near the canyon. Getting to its computer core is the Prisoner's primary objective for this area. However, the crash site is inaccessible due to the ocean of toxic waste and sheer canyon walls.

Uranium Mine
Also critical path - the PC must travel through this area, reactive some of the mining equipment, and tunnel through to get to the B.O.M.B. site.

Cannibal description
About 5ft tall. Oversized cranium springs from normal-sized jaw. Long fingers and nails-turned-claw.

Appearances in games
The Grand Canyon did not appear nor was mentioned (except for a small remark by Harold in Fallout 2) in any of the published games, but was to appear in the canceled Fallout 3 project by Black Isle codenamed Van Buren. It is not certain if it will appear in any future Fallout game, but it is might appear in the upcoming Fallout: New Vegas.
