Sawyer Glacier is deep inside Tracy Arm, a rugged narrow inlet hedged in by towering mountains. A thriving population of stellar sea lions give birth to their young on the icebergs that calve into the 900 feet waters. Because the water is so deep the icebergs do not break apart when they calve off the glacier and as a result the inlet is choked with enormous sapphire blue bergs.

We were lucky enough to be at the glacier the moment a massive piece of ice broke off the face of the glacier and caused a huge boom and a tidal wave the likes I have never seen or heard before. The tiny black dots you see in the impact area are large seabirds, helping to show the sense of scale.
