This Video is a Guide on how to farm the Lynn Woods Legendary Deathclaws that can spawn when you pull the lever. This place doesn't necessarily have to be not clear for this to work, so you can farm while it its [CLEARED]. If you can't get a spawn, go somewhere and wait 7 days, that should reset the place somewhat.
