How does the size of the northwest coast culture region compare to the other three cultural regions?

The Northwest Coast culture region is generally smaller in geographic size compared to the larger cultural regions of the Plains, Southeast, and Southwest. While it has a rich diversity of indigenous cultures and languages, its land area is more confined due to the coastal geography and mountainous terrain. In contrast, the other regions encompass broader expanses of land, allowing for various ecological and cultural adaptations. Despite its smaller size, the Northwest Coast is notable for its complex social structures and artistic traditions.
