In Norse mythology, Jörmungandr (Old Norse: Jǫrmungandr, pronounced [ˈjɔrmunˌɡandr̥], meaning "huge monster"), also known as the Midgard or World Serpent, is a sea serpent, the middle child of the giantess Angrboða and Loki.
According to the Prose Edda, Odin took Loki's three children by Angrboða—the wolf Fenrir, Hel, and Jörmungandr—and tossed Jörmungandr into the great ocean that encircles Midgard. The serpent grew so large that it was able to surround the Earth and grasp its own tai, and hence is an example of an ouroboros. As a result, it received the name of the Leviathan or World Serpent. When it releases its tail, Ragnarök will begin.
Jörmungandr's arch-enemy is the thunder-god, Thor.
Instructions:
The sign at the published co-ordinates specifies a maximum vessel height (MVH) in metres. Anything higher will be eaten by the Jormungandr so it can fit under the bridge over the Colo River.
Use this value (MVH) to calculate GZ where:
South = Published co-ordinates South decimal minutes + (2 x MVH)
East = Published co-ordinates East decimal miuntes + (5 X MVH)
