La Fourche du Trou (Fork of the Hole), better known as Whirlpool River, is that branch of the Athabasca that descends from the Committee’s Punch Bowl on the summit of Athabasca Pass. The first appellation is given because of a peculiar rock formation by which it enters the other branch of the Athabasca through a rocky channel or hole. See our volume vi, p. 353.—Ed.
