Water serves as a primary means of transportation, and as a source of most Tlingit foods. Its surface is flat and broad, and most dangers on the water are readily perceived by the naked eye. Light reflects brightly off the sea, and it is one of the first things that a person in Southeast Alaska sees when they look outside. Like all things, danger lurks beneath its surface, but these dangers are for the most part easily avoided with some caution and planning. For such reasons it is considered a relatively safe and reliable place, and thus represents the apparent forces of the Tlingit world.
