Clarence River (Alaska–Yukon)

Clarence River is a 50 mi long river that flows through Yukon, Canada and the U.S. state of Alaska into the Beaufort Sea.

Course
The Clarence River rises southwest of Mount Paige in Yukon, Canada, and flows northwest and northeast, crossing the border several times into the North Slope Borough of Alaska. It empties into Clarence Lagoon and finally the Beaufort Sea in the Arctic Ocean.

History
The river was surveyed in 1826 by British explorer John Franklin as the westernmost river in the then-British territories on the Arctic coast near the line of demarcation with Russia. Franklin named the river Clarence in honor of Lord High Admiral Prince William, Duke of Clarence and St Andrews.
