I had followed the Yukon River for about 500 kilometres of its over 3 000 kilometre length and been surprised by the strength of its current. Klaune’s glaciers were only one of the sources that contributed to the Yukon’s drive.
Within the mighty river, chinook salmon travelled from the Bering Sea, down to Whitehorse along the Yukon River for 3 200 kilometres to spawn—the longest salmon run. I still can’t grasp how a fish could swim against the powerful Yukon’s force for what must take weeks.
Just out of Whitehorse, the Yukon River poured over a weir with an intensity to be reckoned with. During the spawning season, chinook used the salmon ladder near Whitehorse to finally arrive at their spawning sites.
