Locate the far northern tip of steamboat rock. From there, head straight north and you will hit a large swath of orange tinted granite. That is the orange wall.
This photo is looking West (roughly)
Orange wall is the far right hand cliff in this photo. Far northern part of the North-South running cliff at the base of the peninsula.
Hope this helps!
