Missouri River Valley. The Missouri River flows through the valley, which stretches from the Rocky Mountains in Montana to the Mississippi River in St. Louis, Missouri. The valley is home to numerous National Wildlife Refuges, including the Charles M. Russell National Wildlife Refuge and the DeSoto National Wildlife Refuge, which provide habitat for bald eagles, white-tailed deer, and prairie dogs. The valley is also dotted with National Parks, such as Gateway Arch National Park and Badlands National Park, which attract millions of visitors each year, including those from Omaha, Nebraska, Kansas City, Missouri, and Des Moines, Iowa.

Geography

The Missouri River Valley is a vast and diverse region, covering over 500,000 square miles of land, including parts of Montana, North Dakota, South Dakota, Nebraska, Iowa, Kansas, and Missouri. The valley is bounded by the Great Plains to the east and the Rocky Mountains to the west, and is home to numerous rivers, including the Kansas River, Platte River, and James River. The valley's terrain is characterized by rolling hills, prairies, and badlands, which were shaped by millions of years of erosion and glaciation, including the effects of the Illinoian glaciation and the Pleistocene glaciation. The valley is also home to numerous lakes, including Lake Sakakawea and Lake Oahe, which were created by the construction of dams such as the Garrison Dam and the Oahe Dam.

Climate

The Missouri River Valley has a continental climate, with cold winters and hot summers, and moderate precipitation throughout the year, with an average annual precipitation of around 20 inches in Bismarck, North Dakota, and over 40 inches in Kansas City, Missouri. The valley is susceptible to tornadoes, particularly in the spring and summer months, with Tornado Alley stretching across parts of Nebraska, Kansas, and Missouri. The valley is also prone to droughts, particularly in the western regions, where the average annual precipitation is often less than 15 inches, as seen in Billings, Montana, and Rapid City, South Dakota. The National Weather Service and the National Oceanic and Atmospheric Administration monitor the valley's climate and weather patterns, including the effects of El Niño and La Niña.
