[1] Prior to 1960, there was a waterfall at the end of Trollfjorden, but it was redirected to produce hydroelectricity at a nearby power station.

[2] The Battle of Trollfjord (Norwegian: Trollfjordslaget) was fought in 1890 between the first industrial, steam-driven fishing ships and teams of traditional open-boat fishermen over access to the fjord.

The painting is currently located in the Art Galleri Gunnar Berg on the island Svinøya in Svolvær town.

[5] On his 1971 cruise Bramhill was relieved not to have to repeat the feat – all vessels were barred because of the danger of falling snow, ice and rocks.

The Norwegian pilot, the same man as in 1969, remarked that the Avalon had the distinction of being the largest vessel to enter the fjord.

Avalon had a gross register tonnage of 6,584 and 113 metres (371 ft) long; she carried 750 passengers in her role as a ferry but fewer on cruises.
