TheCarson Mounds (22 CO 505), also known as theCarson Site andCarson-Montgomery-[2][3][4] is a largeMississippian culturearchaeological site located nearClarksdale inCoahoma County, Mississippi, United States, in theYazoo Basin.[5][6] Only a few large earthen mounds are still present at Carson to this day. Archaeologists have suggested that Carson is one of the more important archaeological sites in the state of Mississippi.[3][7]

Radiocarbon dating has shown the site was occupied as early as 1040 CE with the large earthen monuments and villages being constructed at the site after 1200 CE, and significant occupation spanning 1420 to 1660 CE.[7]
Archaeologists suggest that Carson is important because it was either near or part of one of the indigenous polities encountered by the expedition ofHernando de Soto, the earliest European explorers of the southeastern United States in the early 1540s.[8] There is no physical evidence that Carson was visited by de Soto or his men during their westward trek. However, they did pass at the very least within 50 kilometres (31 mi) – 75 kilometres (47 mi) of Carson when they traveled down theMississippi River in July 1543. Some archaeologists and historians have located the polity ofQuizquiz encountered by de Soto in the general location of the Carson site and its neighbors and the polity ofQuigualtam being centered further downstream at theEmerald Phase (1500–1680) of the protohistoricNatchez chiefdom in the Natchez Bluffs region. Others have suggested a more northerly location for Quizquiz at theWalls phase sites nearMemphis, Tennessee. Along with the introduction of Eurasian diseases, the social disruptions caused by de Soto and his men caused native polities to fragment and fall apart. No further European contact with the area happened until the late 1600s when French missionaries and explorers entered the region both downriver from Canada and upriver from theGulf of Mexico, by which time the paramount chiefdoms recorded by de Soto had vanished.[9][10]
Carson was first visited by early scientific explorers and archaeologists in the late nineteenth century, including surveyors for theSmithsonian'sBureau of American Ethnology, Col.Philetus W. Norris andWilliam Henry Holmes.[11][12] The site was located on the Oasis Plantation owned by the Carson family and a map of the landscape and mounds was published in 1894 in the 12th Annual Report to the Bureau of American Ethnology byCyrus Thomas. Subsequent researchers to visit the site include theHarvard LMS survey, Ian Brown, Jay K. Johnson, John Connaway, and Jayur Madhusudan Mehta.[5][3][2]
This map, in addition to research by archaeologists, established the significant scale of settlement at the site. The mounds stretch across an expanse of land over 1.6 kilometres (0.99 mi) in length. In the greater pantheon of Mississippian culture sites, Carson is quite large, and it was incredibly important in local and regional political dynamics.[13]
The Carson Mounds site was listed on theNational Register of Historic Places in 1979.[14]
The mounds are listed on theMississippi Mound Trail.[15]

Carson is located in the northern Yazoo Basin, approximately 500 kilometres (310 mi) north from theGulf of Mexico and 120 kilometres (75 mi) south fromMemphis, Tennessee. The Yazoo Basin is afloodplain of the Mississippi River and features a variety of geomorphic features created bymeandering channels of theMississippi River over the last several thousand years.[16] Carson and the mounds were constructed over acrevasse splay which was deposited by the Mississippi River around 2800 years ago.[7]

The Mississippian culture component of Carson extends east to west approximately 1.5 miles (2.4 km) and north to south 0.5 miles (0.80 km) and covers approximately 150 acres (0.61 km2). When it was first documented in 1894 there were over eighty small earthen mounds scattered across the site; a number only exceeded by theCahokia site in western Illinois. Due to extensive Euroamerican farming techniques since this time, most of these small mounds have been leveled and are no longer visible. The site is presently dominated by five largeplatform mounds, some of which form arrangements around central plazas.[17][18]
These remaining mounds, named Mounds A-F, range in size from 3 metres (9.8 ft) and 12 metres (39 ft) in height. Adjacent to Mound A, there was a large enclosed village where archaeologists have currently recovered well over 30 residential buildings.[7] This 5 acres (0.020 km2) area, located in the northwestern corner of the site, was enclosed on three sides by an earthen embankment and ditch, and on its fourth side by a river.[17]
Excavations have produced evidence offlint-knapping, the production ofstone tools, some of which are consistent with blades and drills found at other major Mississippian mound centers includingCahokia andBottle Creek Indian Mounds.[5] Other evidence of interaction with Cahokia comes in the form of the characteristically CahokianRamey Incised vessels which have been found at Carson. Examples of these vessels can be seen at the Carnegie Public Library inClarksdale, Mississippi.[19]
Examination of human remains found in burials at Carson has also shown that the inhabitants practicedartificial cranial deformation or head flattening. The specific type of deformation is defined as fronto-occipital or fronto-vertico-occipital, the flattening of the forehead and the back of the head. This particular type of body modification is more complex than cranial modification as a byproduct of simply "cradle boarding" infants, and is thought to have been purposely done to show the hereditary elite status of the individuals; since the modifications are made in very early childhood before an elite status could have been gained in other ways.[20]
