of north Great Plains cycles of boom and bust, relentlessly exploiting the resource until it has been depleted or destroyed. After the disappearance of big-game hunters, some archaic groups survived by becoming generalists rather than specialists, foraging in seasonal movements across the plains. The groups did not abandon hunting altogether, but also consumed wild plant foods and small game. Their tools became more varied, with grinding and chopping implements becoming more common, a sign that seeds, fruits, and greens constituted a greater proportion of their diet. Also, pottery-making societies emerged. Introduction of agriculture For most of the Archaic period, people did not transform their natural environment in any fundamental way. The groups outside the region, particularly in Mesoamerica, introduced major innovations, such as maize cultivation. Other groups in North America independently developed maize cultivation as well. Some archaic groups transferred from food gatherers to food producers around 3,000 years ago. They also possessed many of the cultural features that accompany semi-sedentary agricultural life: storage facilities, more permanent dwellings, larger settlements, and cemeteries or burial grounds. El Cuartelejo was the northernmost Indian pueblo. This settlement is the only pueblo in Kansas from which archaeological evidence has been recovered. Despite the early advent of farming, late Archaic groups still exercised little control over their natural environment. Wild food resources remained important components of their diet even after the invention of pottery and the development of irrigation. The introduction of agriculture never resulted in the complete abandonment of hunting and foraging, even in the largest of Archaic societies. Etzanoa Etzanoa is an ancient city, that was founded by the Wichita people in about 1450. Etzanoa is located in present-day Arkansas City, Kansas, near the Arkansas River. In 1601, Juan de Oñate visited the city of Etzanoa. Oñate and the other explorers who accompanied him called the city "the Great Settlement". Etzanoa may have been home to about 20,000 people at the time Oñate and his expedition found and explored the city. Early European exploration and local tribes In 1541, Francisco Vázquez de Coronado, the Spanish conquistador, visited Kansas, allegedly turning back near "Coronado Heights" in present-day Lindsborg. Near the Great Bend of the Arkansas River, in a place he called Quivira, he met the ancestors of the Wichita people. Near the Smoky Hill River, he met the Harahey, who were probably the ancestors of the Pawnee. This was the first time that the
