Historical Features are physical or cultural features that are no longer visible on the landscape. Examples: a dried up lake, a destroyed building, a hill leveled by mining. The term makes no reference to the age, use, or any other aspect of the feature. A ghost town, for example, is not a historical feature if it is still visible.
Civil - A political division formed for administrative purposes (borough, county, incorporated place,
municipio, parish, town, township). Distinct from Census and Populated Place.
