"The origin of the name rests with Capt. George Vancouver who surveyed much of the waters around Vancouver Island in the 1790s. On his survey chart of this particular bay he marked it ‘Foul Bay’ because an anchor would not hold bottom so it was a foul anchorage for ships. The name persisted and was transferred to the British Admiralty Chart 577 in 1864, and was formally adopted in 1924."
Mostly I got lost in a volume that lists all of the natural history collections at the museum at that time and imagining the natural historians in the field and the curators preparing and cataloging. Today one goes to the online search tool with the jillion (and that is not all of them!) specimens in the collection.
