Do they stamp the book in Skagway at the Klondike center?
I learned in AK that orcas are dolphins, not whales. There’s some good AK trivia.
More trivia, what the couple saw: Bubble net feeding.
“Sometimes, they swim in a shrinking circle, blowing bubbles as they go, and together, they are able to force fish upward. It's like a trap—fish aren't able to get out of the bubbles. The way the whales exhale the bubbles also creates a loud and intense sound that also helps with the process—fish can't handle the noise! Teamwork makes for an easier meal, you could say. It's an incredible example of cooperation that scientists say is learned.“ - Alaska collection .com
