From the following text, give me a list of all of the U.S. states, sorted in alphabetical order in a comma-separated list. 

The Sioux are a cluster of Native American tribes who originated in the areas of present-day Wisconsin, Minnesota, Illinois, and Iowa. Since the early nineteenth century, the Great Sioux Nation has consisted of three subgroups: the Eastern Dakota (made up of the Santee and Sisseton), the Western Dakota (the Yankton and Yanktonai), and the Lakota (the Teton or Teton Sioux). These Sioux tribes of today were once part of one of the largest American indigenous groups north of Mexico, second in numbers only to the Algonquian people. In the pre-Columbian era (the time in the Americas from prehistory until significant European influence occurred), the Siouan peoples occupied an immense geographical area of the North American continent, from the Rocky Mountains to the Mississippi River and from the Great Lakes to the Gulf of Mexico. Scholars have been able to connect this disparate and widespread grouping of peoples through language. Long before contact with non-Indians, those who spoke the original Siouan language separated into numerous distinct tribes. Some of these many tribes include the Osage and Crow of the Great Plains, the Winnebago in Wisconsin, the Biloxi on the Gulf Coast, and the Catawba in the Southeast. The name Sioux originates from the Ottawa word na-towe-ssi (which in term was derived from a word from an earlier language meaning “foreigner”); the French wrote it as Nadouessioux. The Sioux subgroup names Lakota and Dakota are Siouan words meaning “friend” or “ally.”
