The remainder of the state consists of: deep temperate rainforests in the west; mountain ranges in the west, central, northeast, and far southeast; and a semi-arid basin region in the east, central, and south, given over to intensive agriculture. Washington is the second most populous state on the West Coast and in the Western United States, after California. It is one of the wealthiest and most liberally progressive states in the country.
