The cave is inhabited by the den mother, which is a special, stronger and rarer version of a night stalker. There are also many young night stalkers in this cavern. The cavern is a small, single crescent-shaped room. To the right is a dead end, and to the left is a large arc that will lead to a dead mercenary and a duffle bag.
The Morning Star Cavern appears only in Fallout: New Vegas.
Behind the scenes
The Morning Star Cavern is located in the same geographical area as the real world Morning Star Mine in the Mojave National Preserve.
It is possible to leave the world map near Morning Star Cavern to the south. Facing south, just walk along the mountain to the left. Use any chance to get a higher path on the stonewall, and soon it will be possible to exit the world map. [verified]

In the southwestern corner of the Ivanpah Dry Lake are a series of flat, tiered rocks leading up to a Nightstalker pack and an opening in the rock wall. Check the Hollowed-Out Rock before entering this dark cavern. This winding cavern curves around past a couple of corpse and bone piles, to a large rear alcove where more Nightstalkers are ready to pounce, near a Mercenary corpse."
