 Bonser named eleven of the canyons and rapids on the Skeena River, using the character of the obstacle as a guide.Among them were the Whirly Gig Rapids, Hornet’s Nest Rapids and the Devil’s Elbow Canyon, where the Skeena rushed directly towards a rock bluff before twisting off to the right.Despite these perils the "Caledonia" operated for seven seasons until the HBC replaced her with a new sternwheeler in 1898, also named the "Caledonia".
