Way: 329733362 is not correct.  https://www.openstreetmap.org/way/329733362

This Way, as drawn, indicates a hole with cliffs all around it, but it's actually a face of a bedrock cliff that slopes up in one direction.  See https://wiki.openstreetmap.org/wiki/Tag:natural%3Dcliff  To correctly indicate a cliff, it should follow the top edge of the cliff (which in the case of these Red Rock mounds is pretty vague).  

This type of outline maybe makes sense as a natural=bare_rock, but still, it wouldn't be applied to each little protrusion of rock, it would cover the whole rock formation.
