Found this one while out collecting a nearby GC cache. Haven’t seen one like this before, it states it is a Department of Main Roads Survey control Mark. Reference number, 901/3 SSM 1908. It was found embedded in a rock over hang with a nice outlook over the Cook’s River. The area is known as Richardson’s Lookout in Marrickville. I would probably give this one a terrain 2.
