The Ramparts (Mackenzie River)

The Ramparts is a 12-kilometre (7.5 mi) canyon on Canada's Mackenzie River, in the Northwest Territories.

Just upstream (south) of the canyon lies the Rampart Rapids, a significant navigational impediment and potentially dangerous to paddlers.

[1] According to the 1968 Great Slave Lake and Mackenzie River Pilot, the rapids lie between mile 672 and 682.

[4] 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.

[5] A scholarly study on climate change discussed how it had led to reduced water levels, which were, in turn affecting navigation.
