If you look out in the distance on a clear day you will see Mt Canobolas.
The road does not appear on all maps but trust me it's there and all vehicles will be able to drive on it.
The cache container will become clear when you find it.
The GPS jumped around a bit when I placed it for some reason and came down to within 5-10 metres. There are plenty of Geoclues and when you pull up most of you will go straight too it. The container and title will become obvious when you find it.
I also highly reccomend going in and looking at Yuringahs grave site. There is one of JMAD1's caches nearby but the area is more then a simple grave marker.
