David Thompson is known for mapping much of which region?

• A. Eastern forests.
• B. Atlantic coast.
• C. Prairies.
• D. Central Canada.

Answer: (D)

David Thompson was a famed fur-trade explorer and cartographer whose work focused on western North America in the late 18th and early 19th centuries. He produced detailed maps of river systems, mountain passes, and vast expanses of plains, linking the Pacific coast with interior trade routes. His most enduring contributions come from charting the western Canadian interior and the Pacific Northwest, including the prairie regions as they meet the Rockies and the coastal areas. This is why the region he’s most associated with is the western Canadian interior, including the Prairies, rather than the eastern forests, the Atlantic coast, or Central Canada (Ontario and Quebec). Thompson’s maps were crucial in guiding later exploration and settlement across those western lands.
