The first step in the process of protection is to name the feature. It does not matter how big or small the area or whether or not features overlap other recognized features.
Natural features are areas that can or have been named after some natural thing in that area.
To name a natural feature after a person or a distant place is to do great disservice to that area. Natural features usually do not contain any animal or plant that is listed on any endangered list anywhere. However, because they are unique, they may contain an unexpected biological diversity.
