This feature class contains salt water polygons. The Forest shoreline originated from the cartographic feature files (CFF). All small islands not in the CFF were digitzed from 1:63,360 paper quads. Columbia Bay was replaced in 1993 with arcs digitized from 1990 CNF aerial photos (approx. scale 1:31680). Valdez Arm and Prince Wiilliam Sound (PWS) are closed with artificial arcs to create the salt water polygon for PWS.
