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.

Detailed walkthrough
head to the quary and kill the alpha male it may or may not be with the mother and children. The mother is with the children no matter what. The children are half the size of a normal deathclaw but the mother makes up for it at 1.5x the size of a normal deathclaw. Bring plenty of AP (armour pircing) rounds because the deathclaw skin counts as armour! after the tageted deathclaws are dead you can return and get your 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.
