seattle is known as the emerald city due to its lush landscapes and abundance of parks. the mild maritime climate ensures moderate temperatures and keeps the city green, allowing outdoor activities to be enjoyed year round. virtually surrounded by water (lake washington to the east, puget sound to the west, and cut through the middle by the ship canal), seattle is a major port city and a hub of international trade and commerce. with the olympic mountain range to the west and the cascade mountain range to the east, seattle is a place like no other.
