Madrox,
I have talked to you before and I think we met yesterday briefly. You got into the Womb just before I left.
The water fall is in Kinley Creek, which is the same creek that flows under the bridge at Highway 173. Water flows in the creek only during winter and spring. Most of the year it is dry.
Here is some info on the range.
