Drifting icebergs near the face of tidewater glaciers often serve as nurseries for harbor seal mothers and their pups. The ice offers a place to birth their young, a place for rest and sunning, as well as a refuge from their main predator, orcas (also known as killer whales). The two most important pupping grounds in Southeast Alaska are John Hopkins Inlet in Glacier Bay National Park and South Sawyer Glacier in Tracy Arm-Fords Terror National Wilderness.
