Sam Demientieff talks about seeing a large whirlpool here a week earlier and how it was undercutting the bank of the sandbar across from the Riverboat Discovery camp. He thought the turbulence of the water and its strong current would keep it open, but it all has refrozen. Processes Observed |
The river channel here is very narrow, and upriver the main channel branches off into three. Difference in current and water depth and what freezes versus what has not frozen. First time having seen such bubbling turbulent water at this spot. Processes Observed |
While standing on the sandbar across from the Riverboat Discovery camp, Sam Demientieff explains "low flow erosion." Erosion that occurs when the river is frozen or just freezing and there is low water and low flow and it is cutting under the sandbar banks. Processes Observed |
