Your extra day at the lodge is a tour with Trapper Rick who is cross Knight Inlet, through Thompson Sound to the Kakweikan River. This remote river is located on the BC mainland and we travel by road, cross a river by boat and a short level hike to Rick’s cabin. Just below the cabin about 200 meters (yards) on the river one is able to sit and overlook and area where the grizzly bears come to fish salmon. The first photo shows guests looking across the river….
From Oxford Journals “Porpoising is the popular name for the high-speed surface piercing motion of dolphins and other species, in which long, ballistic jumps are alternated with sections of swimming close to the surface. The first analysis of this behavior (Au and Weihs, 1980) showed that above a certain “crossover” speed this behavior is energetically advantageous, as the reduction in drag due to movement in the air becomes greater than the added cost of leaping.”
Or Porpoising Definition – Birding and Wild Birds – About.com (verb) The act of leaping in and out of the water in a short, shallow arc while swimming.
