Fortress Pass, is at the east end of Fortress Lake and is on the Continental Divide. It separates the headwaters of the Chaba River in Jasper National Park (Alberta) from Fortress Lake (1333m), in Hamber Provincial Park (British Columbia). It is barely more than a raised gravel bar, and at one time Fortress Lake probably drained out that way, which would significantly alter the BC-Alberta border. The map shows a single 100' contour drop. In winter one skies across Fortress pass without even realizing one has changed watersheds.

<b>Drainages:</b> To the east, the pass drains immediately into the Chaba River, which joins the Athabasca River 7.2km downstream (N). The Athabasca then flows north to the Mackenzie. To the west, Fortress Lake drains into the Wood River, which drops quickly into the Columbia River. The area north of the pass is dominated by Edith Cavell, and to the south, by Mount Columbia.
