The Palliser Expedition (officially the British North American Exploring Expedition) was a major scientific and exploratory mission conducted from 1857 to 1860, led by John Palliser with a team of scientists and surveyors. The primary purpose was to gather comprehensive information about the geography, climate, flora, fauna, and potential for settlement and transportation in what is now western Canada157.
Content and Scope of the Reports
The expedition produced a series of detailed reports and journals, published in 1859, 1860, and 1863, with a comprehensive map following in 1865568. These documents included:
-
Astronomical, meteorological, geological, and magnetic observations
-
Extensive descriptions of the landscape, waterways, and mountain passes
-
Documentation of flora and fauna
-
Ethnographic notes on Indigenous peoples, their customs, and languages
-
Assessments of the region’s suitability for agriculture and transportation
-
Identification of mineral resources, including coal deposits
James Hector’s geological sketches and observations became the foundation for the first thorough description of Canada’s geological structure west of the Great Lakes, providing insights into the earth’s development and comparative ages of rock and soil formations6.
Key Findings and Impact
The reports concluded that establishing a transportation route entirely within British territory from Canada to the Red River would be difficult and expensive, while routes through American territory were more feasible5. The expedition identified a semi-arid region—later called "Palliser's Triangle"—which was not suitable for agriculture, but also mapped out a surrounding "fertile belt" ideal for stock raising and farming51.
The team traversed six major passes in the southern Rockies, evaluating their suitability for railway construction. Notably, Kicking Horse Pass, named by Hector, was later used for the Canadian Pacific Railway51.
Publication and Legacy
-
The main report was presented to the British Parliament in 1863, though its scientific depth led to it being somewhat overlooked at the time67.
-
The expedition’s comprehensive map, published in 1865, became the authoritative reference for the region for many years58.
-
The reports had significant influence on Canadian economic development, settlement patterns, transportation planning, and expansionist policies, as well as on Indigenous communities15.
Surviving Documentation
While some of Palliser’s own papers were lost in a fire, surviving documents, journals, and detailed reports have been compiled and published, notably by the Champlain Society and other archival sources3249. These are still referenced by historians and geographers today.
Summary Table: Key Publications
| Year | Publication Type | Content Highlights |
|---|---|---|
| 1859 | First report | Initial findings, routes, and observations |
| 1860 | Second report | Expanded scientific data and ethnographic notes |
| 1863 | Final report to Parliament | Comprehensive synthesis of all findings |
| 1865 | Official expedition map | Detailed mapping of routes, passes, and discoveries |
Conclusion
The Palliser Expedition reports represent a foundational body of scientific and geographic knowledge about western Canada. They influenced policy, settlement, and infrastructure for decades and remain a critical historical resource156.
