Headwaters: the source of a river or stream.  It is the farthest place in that river from its estuary or joining of another river.  Headwaters is the beginning.  It is the starting point.  It is a tiny stream from which a larger network of streams are born.  It is by nothing short of a Divine Coincidence that NazMoto should have its origin here, in Allen SD.
