There are the ones in the sea .. well off the coast, others are located 
in rivers ... these would be navigation hazards. Not too concerned with 
ones on or even adjacent to land.

With you there .. the 'natural' key is a bad term. Its values should be 
split between landcover and landform. A landform of a peak, saddle etc 
could have a landcover of wood, grass etc.

Humm possibly the landuse key is not what is wanted either ... as it is 
being used on water too ... possibly landuse should be humanuse ?
