Primm Pass

 is a thin pass through the mountains that allows one to walk straight from Primm to Novac without traveling south. This is the map marker for that passage.

Layout
The entrance to the west side of this passage is next to Emergency Service Railyard and the entrance to the east side of this passage is next to Harper's Shack (which is directly NW or behind the shack, but you must actually go SE then head back up around to the West to find it). You are in the right place if you see the REPCONN dome and of course are attacked by the blind Deathclaw.

There is a deathclaw here so be careful. The deathclaw can easily trap you because of its quick speed and you will be stuck.

Exploits
A strategy to avoid direct confrontation with the Deathclaw can be practiced by jumping up a rock incline to the left side of the cliff at the entrance to the pass. If done correctly it is possible to walk/jump down the left side of the valley wall, all the way to the large rock with the Bright Follower body at its base. From there one can jump up and on top of the rock to attack the Deathclaw from an elevated position. This practice seems to apply to most creatures if you are not on the same "level" as them. Approaching from an elevated position seems to prevent them from charging and causes them to retreat from you as it does with the Deathclaw in this instance. (PS3 version)

Bugs
If hit just right with dynamite, the Deathclaw will sometimes launch vertically straight up several stories and drop to its death. (PS3 version)

Appearances
appears in Fallout: New Vegas.
