Round 1
Matches 13 through 16
Frozen Rivers
Match 13: Yukon vs Mackenzie
The Llewellyn Glacier in northern British Columbia is the furthest upstream source of the Yukon River system. The river flows approximately 3,190 km through Canada and the US, draining an area of 854,700 km2. Just over half of the drainage area is in Alaska, draining the central part of the state. Primarily glacier-fed, the Yukon River Basin receives an average of 260 to 300 mm precipitation annually.
Flowing north-northwest through boreal forest, the 1,738 km long Mackenzie River system represents one of the longest river in Canada. Including its tributaries the 4,241 km long river system represents the 13th largest in the world and drains about 20% of Canada to the Arctic Ocean. It also carries the greatest annual load of suspended setiments and dissolved solids of all circumpolar rivers!

Match 16: Yenisey vs Ölfusá
The Yenisey River is the largest river to drain into the Arctic Ocean and fifth-longest river system in the world. 33% of the watershed is permafrost year-round, but permafrost is present in up to 88% of the watershed.
The largest river (by volume) in Iceland, the Ölfusá, which results from the confluence of the Hvítá and Sogið rivers, is fed by glacial meltwater and flows through several famous waterfalls like Gullfoss before draining into the Atlantic Ocean.
