The Palliser Expedition was a British expedition that explored and surveyed the open prairies and rugged wilderness of western Canada from 1857 to 1860. The expedition was led by John Palliser and the party consisted of:
John W. Sullivan, mathematician and sextant observer
After three more years of publishing the details of the expedition, Palliser presented his report to the British Parliament in 1863. A comprehensive map of the surveyed areas was published in 1865. Palliser's Triangle was first explored by this expedition and they reported back that this region was too arid for agriculture, a finding that was overrulled by later officials much to the detriment of those who have tried to farm there.
The PalliserExpedition (British North American Exploring Expedition), 1857-60, was initiated by John PALLISER, who submitted to the Royal Geographical Society a plan to travel from RED RIVER COLONY to and through the Rocky Mountains along the unsurveyed American boundary.
Under Palliser's command, Dr James HECTOR was appointed geologist and naturalist, Eugène BOURGEAU botanical collector and John W. Sullivan secretary and astronomical observer.
The expedition's reports (published in 1859, 1860 and 1863) and its comprehensive map (1865) were for some time the major source of information about the sweep of country from Lake Superior to BC's Okanagan Valley, and are still of value today.
