Source

The Missouri River's source in the Rocky Mountains of Montana is a crucial aspect of its identity as the longest river in the United States. The Rocky Mountains provide the headwaters for the Missouri River, which then flows eastward for 2,341 miles to its confluence with the Mississippi River. The elevation and hydrology of the Rocky Mountains play a significant role in shaping the characteristics of the Missouri River.

The Rocky Mountains are a major mountain range located in western North America. They are the source of many rivers, including the Missouri River, the Colorado River, and the Columbia River. The Rocky Mountains are formed by the collision of the North American Plate and the Pacific Plate. This collision has caused the Earth's crust to fold and thrust upwards, creating the Rocky Mountains.

The Rocky Mountains are a major source of water for the United States. The snowpack that accumulates in the mountains during the winter months melts in the spring and summer, providing water for rivers, lakes, and reservoirs. The Missouri River is a major beneficiary of this snowmelt. The river's headwaters are located in the Rocky Mountains of Montana, where the snowpack is typically deep and reliable. This snowmelt provides a steady flow of water to the Missouri River throughout the year, even during dry periods.

The Missouri River is a vital resource for the United States. It provides water for irrigation, drinking, and transportation. It also supports a diverse ecosystem, including fish, wildlife, and plants. The Missouri River's source in the Rocky Mountains of Montana is a key factor in its ability to provide these benefits to the nation.
