Claws Out

 is an unmarked in Fallout: New Vegas.

Quick walkthrough
Travel to Sloan and speak to Chomps Lewis.

Discuss why the miners are not working and agree to look into the Deathclaw problem at his quarry.

Proceed to Quarry Junction and eliminate the Deathclaw Mother and the Deathclaw Alpha Male.

Return to Sloan and speak to Chomps Lewis to complete the quest and get the reward.

Note
This quest is very dangerous to attempt at a low level. Unless you are a high level (at least 20) or have a safe way of killing the Deathclaw's, you should use caution, and save before attempting.
