Four Skull Lookout is an above ground ruin and lookout point overlooking the Karth River valley. It is a large stone structure with a single room with a domed roof. It is on top of a cliff south of Karthwasten and east of Markarth. Local bandits have set up camp here, and it is one of the few ruins in The Reach that is not inhabited by Forsworn.
This is the final location of the pedestals.
- There is a silver ore vein out back.
- There is a birds' nest out back tucked under a ledge, which contains a Pine Thrush Egg.
- There is a Shrine of Zenithar on an overlook just to the West.
