In Norse mythology, Gálgviðr (Old Norse "gallows-wood") is a forest in Jotunheim, land of the jötnar, from which the rooster Fjalar is foretold to begin crowing during the onset of Ragnarok.
Frederick Delius’ symphonic poem On the Mountains was sketched while the composer was on a walking holiday with Edvard Grieg and Christian Sinding in the Jotunheim Mountains in 1889.
Nór's new kingdom is now said to have been what is south-eastern Norway today, as it extended from Jötunheim mountains in the north to what was later known as Álfheim (roughly the modern Swedish Bohuslän) in the south, the southern border of Nór's land being what is now the Glomma river whose southwestern course is not very far inside the southeastern border of modern Norway.
