On July 4th the Humpback known as Mathematician (BCY0785) gave us some great fireworks before the sun even had a chance to go down.  He was swimming by himself just northwest of Dungeness Spit and he got pretty spirited as a cruise shipped passed by in the distance.  He breached 6-7 times and slapped his pectoral fins on the surface repeatedly too!  Here are a few photos from our experience.  Naturalist/Photographer, Bart Rulon
