Response to More info
Having taken my own advice to check Google Earth, this is what looked somewhat promising to me.
38.752988° 41.346242° - forested canyon where three sides are hills, and one side is open to the Mush plain, and seems like it should have a view of Mt. Sipan as well. There appear to be ruins in this spot, as well as both up and down the road from here. It seems heavily visited from the look of the road. Driving from Mush would be about 20km.
