The Mississippi River is the second-longest river in North America. It rises in northern Minnesota and meanders slowly southward for 2530 miles to the Mississippi River Delta at the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 31 US states and two Canadian provinces between the Rocky and Appalachian Mountains. The Mississippi ranks as the fourth longest and tenth largest river in the world. The river either borders or cuts through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
Mississippi River in Atlantis
The Big Muddy River was the longest river in northern Terranova. In 1843, John James Audubon and Edward Harris sailed down the Big Muddy River to New Orleans, and then out into the Bay of Mexico, across the Hesperian Gulf, and on to Atlantis.
It is unclear whether Big Muddy is slang (as it is in OTL) or the formal name for the river.
Mississippi River in A Different Flesh
The New Nile was the longest river in North America. It originally served as a boundary-line for English colonies, although by the 18th century, most colonists had routinely crossed the river to settle. When the Federated Commonwealths of America declared independence in 1738, the New Nile was entirely within the new nation.
Mississippi River in Southern Victory
The Mississippi River was heavily mined and patrolled by river gunboats belonging to both the USA and the CSA during the Great War. The naval presence on the river and shore defenses made it difficult for either side to advance into the others territory via that route. The Confederates fell back as the US Army captured portions of the riverbank culminating the the bombardment of Memphis by a US force advancing into northeastern Arkansas.
The Mississippi was the site of a rare ship-to-ship river monitor battle in 1916, when the USS Punishment sank a Confederate ship. George Enos served on the Punishment, until it was destroyed in turn. Enos had been ashore visiting a 'house of ill repute' when his ship was attacked and sunk.
