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.
Lake - Natural body of inland water (backwater, lac, lagoon, laguna, oxbow, pond, pool, resaca,
tank, tarn, waterhole).
