A Sea of Sea Lions on South Marble Island
South Marble Island, in Alaska's Glacier Bay National Park, is famous for its colonies of sea lions. Watch these rambunctious showoffs dive off the cliffs, banter with each other, and bask lazily on the rocks.
The area is also a birder's paradise, where you can spot countless varieties of species, including the colorful tufted puffin, black oystercatchers, and majestic bald eagles - just a few of the 240+ species of birds that call the national park their home.
