Category:Hawaii mountains

 has created Category:Hawaii mountains in order to populate Category: Mountains of the United States.  I was wondering if you could take a look at it and make any suggestions, as it seems to be a duplicate of Category:Volcanoes of Hawaii.  My suggestion is that we simply categorize Category: Volcanoes of Hawaii, which we keep as a subcat, and  depopulate the article members of Category:Hawaii mountains.  Wouldn't this avoid a lot of unnecessary duplication?  Let me know what you think.  | Talk
