The Mississippi River, one of the world’s longest rivers, has been a source of wonder and amazement since it was first explored in the 1500s. It has a long and winding course that follows the natural topography of the central United States. It has also served as a vital economic and cultural lifeline for much of the country’s population. Even today, it remains an important highway for trade and transportation of goods. But, perhaps most importantly, it is the source for much of the country’s water. And, in some parts of the river, near its headwaters, it does get cold enough to freeze. <\/p>\n

According to climatologists and geographers, there are stretches of the Mississippi that often freeze during the winter months when temperatures dip below zero. This often varies from year to year as the average temperature of the region can dictate when the river might freeze over. Generally, the earliest recorded freeze over of the Mississippi was in Louisiana in 1910 and the most recent in Minnesota in 2013. Also, the northern parts of the river in Minnesota tend to be colder than the southern parts near Louisiana and tend to freeze more often. <\/p>\n

The science behind the freeze-over is fairly simple. As the temperature around the river dips, the water in the river cools too. Once the temperature of the water is at 32 degrees Fahrenheit, it begins to freeze. This can happen on top of the water, forming an ice sheet, or along the edges of the river. The currents in the Mississippi are slow enough that they cannot combat this phenomenon, though they do help break down and reform any ice that may form. In addition, ice from the tributaries often adds to the coldness of the Mississippi and can contribute to freeze-overs. <\/p>\n

In recent years, scientists have been concerned about the possibility of a more permanent freeze over of the Mississippi, due to the global rise in temperatures. For many communities in the areas around the Mississippi, a freeze-over of the river could pose a serious risk. It would mean that shipping and trading along the river, which is highly dependent on river traffic, would be disrupted. It would also disrupt access to drinking water and endanger the safety of people who depend on the river for their livelihood. According to experts in the field, though, these risks are still very small, since the temperature of the river must reach a much lower level in order to cause a permanent freeze. <\/p>\n
