The 미주리 강 (Missouri River) is the longest river in North America, stretching about 2,341 miles. It flows through several states, including Montana, North Dakota, South Dakota, Nebraska, Iowa, Kansas, and Missouri, before joining the Mississippi River near St. Louis. The river plays a crucial role in the region's ecology and economy. Historically, the 미주리 강 served as a vital transportation route for Native Americans and later for European settlers. It was explored by Lewis and Clark during their famous expedition in the early 1800s. Today, the river is important for agriculture, recreation, and wildlife habitats.
