As the orcas meandered south, the sky around us began to catch fire, the light dancing like the flame of a candle by the window. My job as captain was simple: try to keep the boat as steady as possible to allow my crew to capture this breathtaking scene. Then, just as we hoped, the giant dorsal fin of the bull Orca began to break the surface just in front of that gleaming fireball in the sky. As the whale slid beneath the waves, everyone on board looked at each other and agreed: that was the most beautiful thing we had ever seen.
