Name Notes: Like many of the peaks in Auyuittuq, Mount Baldr takes its name from an important part of Norse mythology.

The name Baldr means "the glorious" and was used by Norse poets to mean a warrior, in honour of the martyred god of youth and beauty in their mythology. His palace in Asgard was named Breidablik, the wide-gleaming, where nothing impure could be and which had a silver roof and golden pillars. His untimely death, which represented the passing of righteousness from the world, was caused by the trickery of Loki after Baldr's mother Frigg had asked of everything in the world that none would harm him. Loki tricked her into admitting that she had overlooked the mistletoe, as it seemed to small to do any harm. Loki crafted a dart out of the mistletoe, and put it into the hands of Baldr's blind brother Hodr, who wished to take part in an event in which all the gods were throwing things at Baldr, since none would hit their target, as all objects or substances thrown were honouring the vow to Frigg. Baldr was killed instantly as the mistletoe dart thrown by his brother (aimed by Loki) pierced his heart and as a result of his death came to rule the cold realm of the dead, Niflheim, as the husband of Loki's daughter Hel (who had been given the job because her half-corpse body was distasteful to the sight of the other gods). Hel rebuked pleas from the gods to return Odin's favourite son, stating that she had a right to have as a husband the youthful and handsome god of beauty, since she had been so unfairly treated for her ugliness and half-giant origin (Loki's wife was the giantess Angrboda - "foreboding" or "resentment"). Hel said upon receiving pleas from Asgard to release Baldr that she would do so if all things in the world would weep for him. Loki, disguised as a giantess named Thokk, refused to do so and thus Baldr remained dead and was cremated on his boat, Hringhorni. The prophecies of the Voluspa say that after Ragnarok, Baldr would return from the dead to rule the world once the other gods had been killed by his in-laws, the giants.

As punishment for his treachery in causing the death of Baldr, Loki was chained to a rock deep in cave within the earth, with a serpent dripping poison onto him for eternity, either into his eyes or into an open wound, depending on the version of the story. Earthquakes were believed to be caused by Loki shaking at his chains in agony from the pain.

Baldr's first wife was Nanna, a name also given to the women who were sacrificed in burial pyres in order to accompany the deceased to the afterlife. The myth of Baldr - a god of righteousness who would return after the end of the world - helped form a basis for the eventual conversion to Christianity at the end of the Viking age.
