These twin massifs cap the end of the 48-kilometer Tracy Arm fjord. Their striking cobalt hue occurs thanks to the dense ice, which absorbs every other color in the spectrum and whose crystalline structure strongly scatters blue light. Larger vessels can only approach the South Sawyer Glacier in good weather, so pack your binoculars and telephoto camera lenses! Make sure to scan the floes at its base for harbor seal pups, especially from May to early July.
