This first chart shows Arran Rapids, Stuart Island, Yuculta and Dent rapids. Mr. Johnstone first ventured through Arran Rapids on the north side of Stuart Island. On his second trip he came through Yuculta Rapids and Dent Rapids, which was the same course we took in Fantasia. The critical factor with these rapids is hitting them within fifteen minutes of slack water, when the tide is turning from flooding to ebbing or the reverse. Soon after the turn, a large whirlpool forms off of Little Dent Island with the imaginative name of Devil's Hole!
The following chart shows the start of our voyage from Bellingham in the lower right, up past Desolation Sound, almost to Stuart Island and Yuculta Rapids. Our course is in red, Vancouver's course in the Discovery is in blue, and Johnstone's course in the open boat is in green as he heads north from Desolation Sound.
This next chart shows from just above Desolation Sound to the Broughton Isalnds. Stuart Island, shown in the first chart on this page, is the small island immediately to the east of Sonora Island at the entrance to Bute Inlet
