It is located beneath the Searchlight west church, and is where Logan and two prospectors can be found hiding from the feral trooper ghouls and harsh radiation on the surface, as Camp Searchlight has recently been irradiated from Legion-perpetrated sabotage.
The Searchlight NCR storage appears only in Fallout: New Vegas.
- Fallout: New Vegas Official Game Guide Collector's Edition Tour of the Mojave Wasteland: Western Chapel, p. 421: "Beware of both Ghouls and Radscorpions in this area. The ruined chapel offers reasonable defensive areas (the walls and doorways) to attack from. At the back is a Cellar Door to Searchlight NCR Storage. Enter the Cellar Door and root around in this root cellar, although three Prospectors (including Logan) have got there first. Logan’s a real piece of work, but if you can stand him, you can team up and begin Side Quest: Wheel of Fortune. Or you can kill him for the keys to the two largest buildings in town. Check the NCR Storage Database Terminal [Average] (as part of the Side Quest) or open the Floor Safe [Average] using Bobby Pins."
