The Berley Lake Infestation is a Lost Lake nest-clearing job with 4 nests to burn. It pays Iron Mike's Camp and sits near the Berley Lake Ambush Camp and the Santiam Tunnel checkpoint. You can clear all three in one trip.
Burn each nest with a Molotov or other fire, throwing from a distance with an exit open. Burning a nest draws the Freakers around it, and daylight means fewer of them are out. Bring at least one Molotov per nest plus spares.
Until the nests are gone, fast travel through this area stays blocked. Opening it makes the trips to the Santiam Tunnel area much shorter.
Deacon remembers this as the point where he and Boozer had to stop searching south. The Santiam Tunnel was choked off and there was no way through.
