Potter Marsh Bird Sanctuary is a 564 acre fresh water marsh, located at the southern end of the Anchorage Coastal Wildlife Refuge.
The marsh was created in 1917 when the embankment for the Alaska Railroad was built up, effectively separating the fresh water from the Chugach Mountains, and the salt water from Turnagain Arm.
Potter Marsh is often called the most accessible wildlife viewing location in Alaska. The marsh is easily reached by the Seward Highway, and it contains a 1550 foot long boardwalk to keep your feet dry.
This wetland maze sees roughly 130 species of migratory and nesting birds calling it home, for at least part of the year. Moose, beavers, muskrats, eagles and hawks all can be viewed at Potter Marsh. Spawning salmon are often seen swimming up Rabbit Creek from Turnagain Arm in season.
Both brown bear and black bear use the marsh, but they are very rarely seen here. Consider yourself very lucky if you spot a bruin moving through the wetland.
