This den has been dug into the side of the mountain, just by the old railway, and is used as home by a pack of coyotes: A den mother with several pups. They will not attack unless the player approaches the cave, eg. to loot the dead Bright Brotherhood member inside.
- The dead ghoul might spawn with a variety of weapons, including a Plasma Defender, plasma rifle, laser RCW, recharger pistol or recharger rifle (level-dependent).
- Lottery ticket: At the mouth of the cave.
Coyote den appears in Fallout: New Vegas.
