Who was the British explorer that surveyed the Pacific coast of North America and discovered Puget Sound?

The British explorer who surveyed the Pacific coast of North America and discovered Puget Sound is George Vancouver. He conducted extensive mapping and exploration of the region during his expedition from 1791 to 1795. Vancouver's work was significant because it added to European knowledge of the Northwest Coast, and his charts remained in use for many years. His exploration helped establish the natural boundaries of North America that would later influence treaties and the understanding of territorial claims in the area.

James Cook, another prominent British explorer, is known for his exploration of the Pacific Ocean and made significant advancements in mapping, but he did not specifically survey Puget Sound. Christopher Columbus primarily explored the Caribbean and is credited with the European awareness of the Americas, which is unrelated to the Pacific Northwest. Henry Hudson is known for his explorations of North America and the Arctic, but he does not have a connection to Puget Sound or the Pacific coast.
