Samson Rock Crushing Plant

This location is used as a makeshift post for 1st Recon if you choose to let them aid you against Driver Nephi During the Quest Three-Card Bounty, they will wait for you to lure him towards them and then open fire. Not much here of interest. Just SW is an unmarked location Sulfur Cave which is an entry to Vault 19.

Samson Rock Crushing Plant is just southeast of Vault 3.

Before the war this plant probibly processed rock that came from Quarry Junction though there is no evedence to conferm this yet (that i know of)
