Evergreen Mills

Evergreen Mills is located just East of Casey's Garage, in the lower left quadrant of the map. Populated by raiders and a super mutant behemoth. The Behemoth is trapped in an electrified fence, which you must first disable in order to kill it. Alternatively, you could take a higher position on either the nearby train cars or the elevated walkway to kill the Behemoth. There is also a foundry in evergreen mills which hosts a bazaar where the barter Vault Boy Bobblehead can be obtained.

In order to free the slaves you need to obtain the Evergreen Mills slave pen key from one of the raiders.
