What were the resources David Thompson find?

David Thompson, the renowned Canadian explorer and fur trader, is best known for his extensive mapping of North America's interior, particularly the Canadian Rockies and surrounding regions. He identified and documented various Natural Resources, including valuable fur-bearing animals, waterways for trade routes, and rich agricultural lands. His explorations also revealed mineral deposits, which later contributed to the economic development of the areas he surveyed. Thompson's work laid the groundwork for future exploration and resource extraction in Canada.
