Fenn's Gulch Mine is one of several unmarked mines near Karthwasten. It is located to the northwest of Karthwasten Hall and southwest of Sanuarach Mine.
There is one silver ore vein in the northwestern corner, on the ground.
- A smelter just outside the entrance of the mine.
To the southwest of the mine, slightly up the hill at the base of a cliff, is an unmarked point of interest: Totem to Peryite, which is just below the Shrine to Peryite.
