In Rise of the Machines timeline, After realizing Skynet was taking control over the military force and about to start the nuclear war, General Robert Brewster told John Connor and Kate Brewster to go to Crystal Peak. John and Kate misunderstood General Brewster and believeed they can shut down the core system of Skynet there. John Connor, Kate Brewster, and the T-850 head to Crystal Peak in order to destroy Skynet, only to find out that Skynet is not located here.
In T2 Saga timeline, Kate Brewster was killed in 2007 and John Connor placed her body in the morgue. After Kate's death, John became extreme frustrated, even so desperate that he decided to stay in the bunker to keep him away from the War. However, in 2009, the cooling unit inside Crystal Peak had failed to a point that John was unable to repair it. Hence, John Connor finally decided to leave the bunker for Los Angeles to face his destiny.
- In Terminator 3: The Redemption, it was the T-850 who brings up Crystal Peak as a place of refuge immediately after escaping from the T-X at the cemetery. Then, the group head to Edwards Air Force Base to obtain a plane to fly the 50 miles there.
Behind the ScenesEdit
- In the reality, Crystal Peak is around 440 miles away from the Edward Air Force Base  instead of 52 miles, which is about the distance between the Edwards AFB to Sierra Nevada mountain range.
- In an unfinished alternate ending to Terminator 3: Rise of the Machines, Skynet Central Core was indeed located at Crystal Peak and it was destroyed by a second T-850. It is assumed that Terminator 3: Fragmented is set in a timeline, which follows this ending.
