El Charro Café is the oldest Mexican restaurant in the U.S. continuously operated by the same family. It may also be the birthplace of the chimichanga. As the legend goes, they were invented by Monica Flin, who established the Tucson restaurant in 1922, when she accidentally flipped a burrito into the fryer, splattering oil everywhere. Since kids were within earshot, she resisted the urge to curse and yelled "chimichanga", a slang word that means thingamajig, instead.

Fifty thousand years ago, a giant fireball streaked across the North American sky. The meteorite weighed 300,000 tons and traveled at a speed of 26,000 miles per hour (12 kilometers per second). When it struck the earth approximately 37 miles east of what is now Flagstaff and 18 miles west of Winslow in the northern Arizona desert, it exploded with the force of 2½ million tons of TNT, or about 150 times the force of the atomic bomb that destroyed Hiroshima. When the dust settled, what remained was a crater three-quarters of a mile (about 1 kilometer) wide and 750 feet deep. Formerly known as the Canyon Diablo Crater, it has since been renamed the Barringer Crater in honor of Daniel Barringer, who first recognized that it was produced by a meteorite impact.

Unless you're a homesteader, a Sunbelt resident who eats only food from your local farmers market, or an extremely devout carnivore, you've almost certainly eaten lettuce from Yuma, Arizona. In fact, the Yuma area produces about 90 percent of all lettuce grown in the United States from November to March, when it's too cold to grow produce in most of the rest of the country.

The state flower is the white blossoms of the saguaro, which appear on the tips of the long arms of the cactus during May and June.
