Located at the southern end of the Anchorage Coastal Wildlife Refuge, the 540-acre Potter Marsh offers easy access to nature, with a 460-meter-long wheelchair-accessible wooden boardwalk. The marsh formed after the construction of an embankment to protect the railroad tracks here from Turnagain Arm’s high tides. The wetlands are home to muskrats, moose and a variety of birds including eagles, northern pintails, canvasback ducks, red-necked phalaropes, trumpeter swans, horned and red-necked grebes, northern harrier hawks and Canada geese. From May to August, spawning salmon can be seen in Rabbit Creek.
