On the morning of Monday, October 12, 1931, early risers in northern Portland noticed a strange creature with smooth black skin in Columbia Slough, right next to the Jantzen Beach Amusement Park. Locals debated its identity. Some argued it was a sturgeon, others a sei whale all the way from Japan. Finally, an old salt tagged it as a small “blackfish.” News of the novelty spread like wildfire, drawing thousands of spectators and causing gridlock on the interstate bridge between Portland and Vancouver, Washington. A local newspaper warned that killer whales were one of the ocean’s “most vicious” creatures, but this one promptly stole Portland’s heart. “From the looks of things,” declared Deputy Sheriff Martin T. Pratt, “nearly everyone in the city is determined to see the visitor,” and when some locals began shooting at the animal, Pratt and his men arrested them. The number of sightseers grew each day, and that weekend, tens of thousands crowded into Jantzen Beach to catch a glimpse of the whale, while enterprising fishermen charged twenty-five cents for whale-watching rides. By that time, someone had dubbed the orca Ethelbert, and the name stuck. Why the little whale had arrived there, a hundred miles up the Columbia, remains a mystery. It had probably become separated from its mother and lost its bearings, wandering up the great river that divides western Oregon from Washington State. But Columbia Slough was no place for an orca. In addition to lacking salt water, it was the main outlet for Portland’s sewage. In summer, the waterway grew so foul that workers refused to handle timber passing through it. As the days passed, observers grew worried. The whale seemed sluggish, and its skin began to show unsightly blotches. The owner of Jantzen Beach proposed capturing the animal with a net and placing it in a saltwater tank. It would have been an extraordinary attraction for his amusement park—already known as the Coney Island of the West. But members of the Oregon Humane Society denounced the scheme as rank cruelty. Instead, they proposed blowing the young orca up with dynamite.
