Archaeologists have also suggested that Carson is important because it was either near or part of one of the provinces visited by some of the earliest conquistadors in the southeastern United States. There is no physical evidence that Carson was visited by Hernando de Soto and his men during the westward trek across the southeastern United States. However, they did pass at the very least within 50 – 75 km of Carson and the social disruptions caused by Soto and his men did cause native polities and provinces like Carson to defragment and fall apart .
