The Deathclaw's lair is a cave near the Hub. In 2161, it is home to one of the fearsome deathclaws.
The only person in the Hub who knows where this cave is located is the insane Slappy. After discussing the deathclaw with the mutant Harold, Slappy can fast travel you to the cave. Inside the cave, aside from the deathclaw itself, there is a dying mutant. He holds a mutant transmissionsholodisk and a radio.
