North Pacific Coast Isolation

 The North Pacific Coast which goes from the Northern tip of California up through Canada and Alaska has many large mountain areas covered in shrubs and trees. This region makes up about 50% of the lumber that the United States uses for building construction. The Douglas fir found in this area is most often used to build strong houses or for plywood. Sequoia’s upper region is also covered in large amounts of Douglas Fir’s along with Redwoods, and Sequoia trees. These trees are not like the maple trees or plan trees that are seen in megalopolis or other high populated areas. These trees are some of the tallest in the world with thick bark that can hold even the strongest lighting strike or fire. In these areas of lush trees there are often lower populations, they are often isolated. Alaska is greatly isolated from the rest of the United States much like the Sierra Nevada’s high mountain ranges are isolated from most of California’s over populated areas. Much like Sequoia’s most of Alaska if still protected by its government and environmentalists so that it cannot be destroyed by people.
