How did geographic conditions in the pacific northwest shape the culture of the native americans there?

The geographic conditions in the Pacific Northwest shaped the culture of the Native Americans by forcing them to adopt thick and warm clothing, and making them eat a high-calorie diet which would allow them to sustain cold temperatures.

Owing to the geographic conditions and the latitudinal orientation of the Northwest Pacific, the climatic conditions there are characterized by the prevalence of wet and cold weather. The people in this region mostly followed fishing with seafaring dugouts. The quarter of the tribes in this region were salves.  

Thus, the cultures of the inhabitants of the region have evolved to adopt warm clothing and calorie-rich food.
