In which area did native American groups hunt with harpoons the north west or the southwest?

Native American groups primarily hunted with harpoons in the Northwest region of North America. This area, characterized by its coastal environment and abundant marine resources, saw tribes such as the Haida and Tlingit using harpoons for fishing and hunting sea mammals like seals and whales. In contrast, the Southwest region is more arid and did not have the same reliance on harpoon hunting.
