Seals are big fans of Holkham Bay and often appear on ice floes that break off of the tidewater Sawyer Glacier at Tracy Arm. The Arm is one of the spots where the massive Stikine Icefield comes down to the ocean. Along much of Stephens Passage, the glacier seems to blend with clouds and is hard to see through the fog. Humans aren’t the only ones with problems of perception here: Seals love the ice because it gives off confusing signals to an orca’s echolocation. The ice floes are like the safe spot in a very high-stakes game of hide-and-seek.
