The Quinlan Mountains is a mountain range in the U.S. state of Arizona. Its highest point is Kitt Peak at 6,883 feet (2,098 m), which is also the second-highest peak on the Tohono O'odham Indian Reservation, after Baboquivari Peak. The range lies on the eastern end of the reservation about 55 miles (89 km) southwest of Tucson.

The Quinlan Mountains are north of the Baboquivari Mountains, the two ranges separated by the pass at the head of the Pavo Kug Wash. The Quinlan range also sits southwest of the Coyote Mountains, separated from them by the Pan Tak Pass. When George J. Roskruge created the official map of Pima County in 1893, he named the range after James Quinlin, who had opened a stagecoach station in the nearby town of Quinlin in 1884. Although the range had also been known as the Quinlin or Quinuin mountains at different points in history, Quinlan became the official name as a result of a decision by the Board on Geographic Names on April 16, 1941.

The Santa Catalina Mountains, commonly referred to as the Catalina Mountains or the Catalinas, are north and northeast of Tucson, Arizona, United States, on Tucson's north perimeter. The mountain range is the most prominent in the Tucson area, near Catalina Foothills, an unincorporated community, with the highest average elevation. The highest point in the Catalinas is Mount Lemmon at an elevation of 9,157 feet (2,791 m) above sea level and receives 18 inches (460 mm) of precipitation annually.

Originally known by the Tohono O'odham Nation as Babad Do'ag, the Catalinas were later named in 1697 by the Italian Jesuit Eusebio Francisco Kino in honor of Catherine of Alexandria who was the patron saint of Kino's oldest sister.

The Madrean region (named after the Sierra Madre Occidental) is a floristic region within the Holarctic kingdom in North America, as delineated by Armen Takhtajan and Robert F. Thorne. It occupies arid or semiarid areas in the southwestern United States and northwestern Mexico and is bordered by the Rocky Mountain floristic region and North American Atlantic region of the Holarctic kingdom in the north and in the east, Caribbean region of the Neotropical kingdom in the south.

The Madrean region is characterized by a very distinct flora with at least three endemic families (Fouquieriaceae, Simmondsiaceae, and Setchellanthaceae). Crossosomataceae, Garryaceae, Lennoaceae, Limnanthaceae and Stegnospermataceae have their principal development here; for Onagraceae, Polemoniaceae and Hydrophyllaceae it is the major center of diversity. More than 250 genera and probably more than half of the species of the region are endemic to it according to Takhtajan.

The Arizona Sun Corridor, shortened Sun Corridor, is a megaregion, or megapolitan area, in the southern area of the U.S. state of Arizona - comprising approximately 85 percent of the state's population. The Sun Corridor is comparable to Indiana in both size and population. It is one of the fastest growing conurbations in the country. The largest metropolitan areas are the Phoenix metropolitan area – Valley of the Sun, and the Tucson metropolitan area – The Old Pueblo. The regions' populace is nestled in the valley of a desert environment. Similar to Southern California, the urban area extends into Mexico, reaching the communities of Heroica Nogales and Agua Prieta.

Its population is composed of five metropolitan areas: Phoenix, Tucson, Prescott, Sierra Vista-Douglas and Nogales. Of these, two are metropolitan areas with over 1,000,000 residents: the Phoenix metropolitan area with 4.85 million residents and the Tucson metropolitan area with over 1 million residents. The Arizona Sun Corridor is made up of all of Maricopa, Pinal and Pima counties, along with parts of Yavapai, Santa Cruz and Cochise counties. It is home to over 86 percent of Arizona's population.
