In topography, prominence (also referred to as autonomous height, and shoulder drop in US English, and drop in British English) is the relative height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. The key col ("saddle") around the peak is a unique point on this contour line and the parent peak (if any) is some higher mountain, selected according to various criteria.

Washington is a state in the Pacific Northwest region of the United States. It is often referred to as Washington state to distinguish it from the national capital, both named after George Washington, a U.S. Founding Father and the first U.S. president. Washington borders the Pacific Ocean to the west, Oregon to the south, and Idaho to the east and shares an international border with the Canadian province of British Columbia to the north. Olympia is the state capital, and the most populous city is Seattle.
Washington is the 18th-largest state, with an area of 71,362 square miles (184,830 km), and the 13th-most populous state, with a population of just less than 8 million. The majority of Washington's residents live in the Seattle metropolitan area, the center of transportation, business, and industry on Puget Sound, an inlet of the Pacific Ocean consisting of numerous islands, deep fjords and bays carved out by glaciers. The remainder of the state consists of deep temperate rainforests in the west; mountain ranges in the west, center, northeast, and far southeast, and a semi-arid basin region in the east, center, 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. Mount Rainier, an active stratovolcano, is the state's highest elevation at 14,411 feet (4,392 meters), and is the most topographically prominent mountain in the contiguous U.S.
