Two burned-out cars can be found, along with three campers making a circle around a table in the middle.
The campground is populated by up to six creatures, most often green geckos and cazadores. There are three trailers, with one containing a bed. White Legs often hide around the camp area and will ambush the Courier.
Mesa crash site
Northwest of Patriarch's campground is a crashed pre-War airplane resting atop a high mesa, with scattered aircraft parts, skeletal remains, and supplies below. The plane's cargo can be found scattered on a ledge above the Zion Canyon river. Landing gear and a wing section can be seen higher up on a rocky outcropping. Farther west around the mesa is a semi-circle of skeletal remains, sacks of gear, and assorted consumables.
It is not possible to reach the airplane itself without the use of console commands.
Behind the scenes
The campground, along with the nearby Court Fork overlook, corresponds with the real world Court of the Patriarchs.
