The Ramparts (Mackenzie River)

The Ramparts are rapids in a 12-kilometer (7.5 mi) canyon that forms a navigational impediment on Canada's Mackenzie River, in the Northwest Territories.[1] The river narrows from almost 2 kilometers (6,600 ft) wide to barely more than 100 meters (330 ft).[2]

The river's only other rapids, the Sans Sault Rapids, are found 56 kilometers (35 mi) upstream.[1] According to the 1968 Great Slave Lake and Mackenzie River Pilot, the rapids lie between mile 672 and 682.[3]

Early explorers for the North West Company reported that Stone Age "eskimo" were known to have ascended the river as far as The Ramparts, in search of flint, to make stone tools.[4]

Although a portage is not necessary, they are best skirted by keeping to the west/left side of the river. There is a sign posted here to warn all boaters of this rapid.
