This is an old proposal that have been discussed before. It seem to be in use according to tag watch, so I have been urged to make this official.
There are also similar tags in use and others proposed but that doesn´t mean this one could be approved. http://wiki.openstreetmap.org/wiki/Proposed_features/bare_rock _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
