The Methye Portage or Portage La Loche in northwestern Saskatchewan was one of the most important portages in the old fur trade route across Canada. The 19 km (12 mi) portage connected the Mackenzie River basin to rivers that ran east to the Atlantic. It was reached by Peter Pond in 1778 and abandoned in 1883 when steamboats began running on the Athabasca River with links to the railroad. It ranks with Grand Portage as one of the two most important and difficult portages used during the fur trade era.
