Quadripoint
The Four Corners Monument is the only point in the United States where four states meet: Colorado, Utah, New Mexico, and Arizona meet at right angles. The United States first acquired the area now called Four Corners from Mexico after the Mexican–American War in 1848. In 1863 Congress created Arizona Territory from the western part of New Mexico Territory. The boundary was defined as a line running due south from the southwest corner of Colorado Territory, which had been created in 1861. By defining one boundary as starting at the corner of another Congress ensured the eventual creation of four states meeting at a point, regardless of the inevitable errors of boundary surveying.

Native American cuisine
Ancestral Puebloans of the present-day Four Corners region of the United States, comprising southeastern Utah, northeastern Arizona, northwestern New Mexico, and southwestern Colorado practiced subsistence agriculture by cultivating maize, beans, squash, and sunflower seeds. They utilized locally available wild resources such as pine nuts from the Pinyon pine, and hunted game including mule deer, hare, rabbits, and squirrel. Ancestral Puebloans are also known for their basketry and pottery, indicating both an agricultural surplus that needed to be carried and stored, and clay pot cooking. Grinding stones were used to grind maize into meal for cooking. Archaeological digs indicate that they had domesticated turkeys which served as a food source.
