The Western Lowlands are in western Washington State. They surround the Puget Sound and include the San Juan Islands. The Lowlands stretch from the Canadian border to the Oregon border.

The Western Lowlands were carved out by glaciers in the last Ice Age. Before that, the lowlands were a series of river valleys. They are hilly and have a lot of water in them. There are a lot of trees and plant life in the lowlands.

The Western Lowlands are cool and rainy in the winter and warm and sunny in the summer. The lowlands have lots of precipitation. Seattle (which is in the lowlands) is known for its rain. The annual precipitation

of the lowlands is 30-50 inches.

The Western Lowlands have some agriculture. They grow peas, carrots, cauliflower, broccoli, mint, artichoke, blueberries, blackberries and raspberries. Some areas of agriculture are the Skagit River Valley, which grows potatoes, flowers/bulbs, vegetables, and dairy products. Around the edge of the central Puget sound area,  dairy cattle and  chickens are raised, and berries are grown. Other agricultural areas are the Chehalis River Valley and the Cowlitz River Valley.
