Tallurutiup Imanga means the waters surrounding Tallurut (Devon Island).
In 1818, John Ross entered Lancaster Sound searching for the Northwest Passage. He saw a mountain range in the distance and believed he was in a bay, so he turned back. It turned out to have been a Fata Morgana, a mirage in the sky, common in the arctic. In 1819, William Parry returned to the sound.
Devon Island
Devon Island is the largest uninhabited island in the world (55,247 sq km), and Canada's sixth largest island. Dominated by the Devon Ice Cap, rising to 1,920m, it has some of the oldest exposed rocks in the world, Precambrian Gneiss (2.5 billion years old), which Marc St-Onge was happy to point out.
Using a Chronostratigraphic Chart, Marc St-Onge points out the 2 billion year Great Unconformity gap between the Precambrian Neo-archean Gneiss and the Ordovician Limestone seen in the cliffs opposite, a product of the Snowball Earth period of global glaciation.
The polar landscape is so similar to Mars that it is the site of NASA's Haugton-Mars project, a planetary analogue research base near the Haugton Impact Crater.
