Summerlin

Summerfell (conjecture, due to the image being unclear) is a location in the Mojave Wasteland in 2281.

Background
Located south west of Vault 22, it appeared on an early map of Fallout: New Vegas.

Appearances
Summerfell was cut from the final version of Fallout: New Vegas.

Behind the scenes
Summerfell is similarly located to real world Summerlin, Nevada and likely reads as such in the early map. Summerlin was named after Jean Amelia Summerlin, the grandmother of Howard Hughes, the inspiration for Robert House.
