A mountain named Sorrei after it was used to make a vault; but after a few months of construction it was put on hold & then completely abandoned altogether when it was decided construction would not be completed in time of the 'big bang'.
The tunnels of numerous caverns both man-made or natural had survived most of the the blasts leaving a very suitable living space for all sorts of nocturnal living ghouls, creatures, or hide-away human slaves, etc,.
This is however the top side of the mountain of Sorrei, where only the most keenest of eyes can find the entrances of the caverns less they rely on other senses to guide them.... Raising at about 7,320 feet high with rugged steep cliffs and rocky climes throughout spotted areas of plant life who continue to struggle to live on from low radiation.
