My stay in British Columbia has resulted in a revisualization of the killer whale. 
I no longer focus on the charming faces of these great dolphins, a consequence of underwater viewing
areas in marine parks and popular movies.  Instead, orcas are tall, black dorsal fins marked with gray saddle patches. 
 Images of glossy black fins slicing through serene blue waters before a backdrop of old-growth
 temperate rainforests will stay with me forever.  If you venture to British Columbia,
you will come to see orcas as “black knives”, with the sea as their sheath.
