North of the Arctic Circle, the monument forms 70 miles of shoreline on the Chukchi Sea. More than 114 beach ridges provide evidence of human use for 5,000 years. The Inupiat continue to use the area today. Vast wetlands provide habitat for shorebirds from as far away as South America. Hikers and boaters can see carpets of wildflowers among shrubs containing wisps of qiviut from muskoxen.
