Prosperidad is an area that has many destroyed and abandoned buildings, a water tower, many Chicken God Totems, a Confederate Dollar (near the cemetery), an Anti-Vampire Tonic, some Bandit's Map Pieces, and many dreamcatchers. Every time you arrive to this area, three or two foxes will appear to kill you, and there is usually a snake at the road sign. This is an abandoned town. Also, graves in Prosperidad have a 45% chance to spawn Nightwalkers and Werewolves.
There are Old Callahan's Seeds and Indian Joe's Prospector Office signs on two buildings, which are abandoned. They may have moved to Socorro Town, where they are seen again.
