There is no river connecting the Canadian Rockies to the Bering Sea via Alaska. This is a geographic impossibility due to continental divides and drainage patterns.
| Destination | Major Rivers | Source Ranges |
|---|---|---|
| Arctic Ocean | Mackenzie (4,241 km) | Rockies (via Peace/Athabasca) |
| Pacific Ocean | Fraser (1,375 km), Columbia (2,000 km) | Rockies, Cascades |
| Hudson Bay | Nelson (2,575 km), Churchill | Rockies, Shield |
| Bering Sea | Yukon (3,190 km), Kuskokwim (1,165 km) | Coast Mtns, Alaska Range |
The Yukon River is the great Bering Sea drainage. Its headwaters are in the Coast Mountains of British Columbia (Atlin Lake area) — a separate range west of the Rockies, across the Rocky Mountain Trench.
