Palliser('s) triangle 
See 1952 quote.
- 1863 This central desert extends, however, but a short way into British territory, forming a triangle having for its base the 49th parallel from longitude 100° to 114° W with its apex reaching the 52nd parallel of latitude.
- 1937 The famous Palliser triangle (indicating the portions not suitable for cultivation) may be compared with the map recently published by a well-known statistical firm.
- 1952 In 1857 The British Colonial Office sent Captain John Palliser to examine and report upon the area. During the years 1857 to 1860, he travelled from Lake Superior to beyond the Rocky Mountains. As a result of his explorations, he divided the plains into two parts, a "fertile belt" and the "true prairie" which he regarded as a semi-arid desert. The latter area, according to him, embraces most of what is now the southern parts of both Saskatchewan and Alberta. In spite of the fact that it is an irregular, five-sided area, it is often referred to as "Palliser's triangle."
- 1958 The affected area includes the eastern half of what is called Palliser ' s Triangle, 28,000,000 acres of semi-arid country stretching from Manitoba to the Rocky Mountain foothills.
- 1863 This central desert extends, however, but a short way into British territory, forming a triangle having for its base the 49th parallel from longitude 100° to 114° W with its apex reaching the 52nd parallel of latitude.
