Been looking at the Mackenzie river and it's starting to break ice cover some 700-800 km from the coast. But near the small town of Tsiigehtchic (some 150 km from the coast) the Arctic Red River seems to have cleared itself.
Just 10km downstream from Tsiigehtchic the Mackenzie river exits the low hills (moraines) and there, to the east of the river, a lot of water seems to be accumulating. I've marked the edge of the moraines with red, the black area to the northeast is probably water.
In Norway the melt is off to a cracking start, as show in the video in
this article.
EDIT: The black lettering disappears, but the arrow points at Tsiigehtchic, at the confluence of the Mackenzie and the Arctic Red River.
