A ravine that is perfect for setting an ambush. The sides fall steep and the remaining stony debris not only serves for hiding but also as material to drop on targets. It is only 10 yards apart at its narrowest point and 50 feet high. It is about 1/4 of a league long. The garguns know about this and will lure intelligent creatures, such as men and dwarfs, here. The ravine can also serve to hide troops and passing through it significantly reduces the time someone will travel to (or from) Zhakom, since a lot of climbs and descends in rough terrain is bypassed.
