What does the Geographic Names Information System (GNIS) classification "historical" mean?

The term "historical" as used in the GNIS means specifically and only that the feature no longer exists on the landscape. It has no reference to age, size, condition, extent of habitation, type of use, or any other factor. For example, a ghost town is not historical, only abandoned as might be noted in the historical notes field. Most historical features are (or were) man-made, but also can be natural features such as shoals that are washed away by a storm or a hill leveled by mining activity.
