The document summarizes the journey of the Mississippi River from its source at Lake Itasca in Minnesota to its mouth at the Gulf of Mexico. It describes the river's source as clear water where you can wade across. It also tells the legend of Paul Bunyan creating Lake Itasca and the Mississippi River. Additionally, it mentions how development has damaged wetlands and contributed to their disappearance of 25 square miles per year in the Mississippi River delta region.

2. The source In the vast pine forest of northern Minnesota is the beginning of the great river known to all the world as the Mighty Mississippi. At the Mississippi's source at Lake Itasca, the water is transparent and beautiful. You can actually remove your shoes and wade to the other side, or drop a twig in the water and imagine it floating to New Orleans.

3. The Legend of Paul Bunyan Only the great outdoors was big enough to accommodate Paul, and it was natural that he should become the World's Greatest Lumberjack.In the year of the 'Blue Snow' when it was so cold the geese flew backward, Paul found a baby ox in the snow. It was so cold, the ox and snow was blue. After Paul took him home and warmed him, his color stayed blue. Paul named him Babe. Like Paul, Babe grew fast and soon was seven ax handles and a plug of tobacco wide between the eyes. For a between meals snack, Babe would eat thirty bales of hay, wire and all. It took six men with picaroons to pick the wire out of his teeth. Babe hauled the huge camp tank wagon which was used to pave the winter logging roads with ice. When it sprang a leak one day, it created Lake Itasca south of Bemidji and the overflow trickled down to New Orleans to form the Mississippi River.

7. Polluting the Gulf of Mexico The Minnesota River (lower branch), bearing sediments and nutrients, enters the Mississippi River at Fort Snelling State Park. These pollutants contribute to the “dead zone” in the Gulf of Mexico. Dead Zone

31. Vanishing wetlands Over the past century, the nearly 1.3 million square mile watershed of the Mississippi River has experienced major environmental changes, including conversion of more than 80 percent of forested wetlands to agriculture and urban areas, channelization, dam construction, and river levees. The construction of massive structures that keep the river from switching channels has restricted sediment and freshwater supply to the flood plain.

32. Unintended consequences These changes have been especially damaging to the region's wetlands. The coastal wetlands associated with the Mississippi River delta make up nearly 40 percent of the total coastal salt marsh in the lower 48 states of the U.S. These wetlands are disappearing at an average rate of 25 square miles per year, about 50 acres each day. Fragile wetlands are readily damaged, directly and indirectly, by canals dredged for navigation and energy exploration.

34. Drilling for oil Over the last 100 years, Louisiana has lost over 400,000 hectares to open water. Prior to 1940, the majority of Louisiana's oil and gas fields were in freshwater. Subsidence, the rise in sea level, and loss of land have contributed to all but one oil field now being located in open saltwater. All of these fields are vulnerable to oil spills, particularly those directly offshore.

35. Technology pushes exploration Since the mid-1990s, the Gulf has experienced a resurgence, with computer-driven technological advances — and federal tax breaks on the royalties paid for drilling in leased government waters — opening new horizons in water as deep as 10,000 feet, hundreds of miles from shore. .
