Ayres Rock/Uluru is supposed to be 1 big lump of sand stone. http://upload.wikimedia.org/wikipedia/commons/f/fc/Uluru_%28Helicopter_view%29-crop.jpg You also have the cores of what were volcanoes, the outer dirt layer has eroded away completely over time http://lh3.ggpht.com/_PBYeriHIc4k/SfT3VgN4yvI/AAAAAAAAA0A/GKwEHYMKEcI/P1010343.JPG Just to throw a spanner in the works, both of which are natural formations :) As for loose rock, isn't that scree? _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging -- John F.
