Scottsdale was originally inhabited by Hohokam. From circa 300 BC to 1400 AD, these ancient civilizations farmed the area and built some of the most ingenious irrigation canals the world has ever known. The name Hohokam translates as "vanished," as the civilizations mysteriously disappeared without a trace. Before Anglo settlement, Scottsdale was a Pima village known as Va?ai Sva?on?, meaning "rotting hay." Some Pima remained in their original homes well into the 20th century. For example, until the late 1960s, there was a still-occupied traditional dwelling on the southeast corner of Indian Bend Rd. and Scottsdale Rd. By now, however, all Pima have either moved into modern homes within Scottsdale (mainly in South Scottsdale), to the Salt River Pima-Maricopa Indian Community, or elsewhere. The Hohokam's truly unbelievable (and many do not believe it?) legacy was in their creation of more than 125 miles (200 km) of canals to provide water for their agricultural needs. The remnants of this ancient irrigation system were adapted and improved upon in 1868 by the first Anglo company to stake a claim in the Valley of the Sun, when Jack Swilling set up the Swilling Irrigation Canal Company. Twenty years later Scottsdale's future would turn sharply upwards, when a U.S. Army Chaplain, Winfield Scott, paid the paltry sum of $2.50 an acre for a 640 acre stretch of land where the city is now located. Winfield's brother, George Washington Scott, was the first resident of the town that was then known as Orangedale and later changed to Scottsdale in 1894. In 1937, internationally renowned architect Frank Lloyd Wright set up his "winter camp" at the foot of the McDowell Mountains, creating what is now known as Taliesin West. Scottsdale, and the rest of Phoenix, have seen an everlasting influence from Frank Lloyd Wright. Many buildings throughout the region were designed by the famous architect. Today, a Frank Lloyd Wright memorial stands in North Scottsdale and a major street bears his name. In 1951 the Town of Scottsdale was officially incorporated with a population of 2000. Since then it has grown to a 2004 Census estimate of 221,792. It is now Arizona's fifth-largest city, and one of its most celebrated. Scottsdale is commonly defined by its high quality of life, and in 1993 was named the, "Most Livable City," in the United States by the United States Conference of Mayors."http://www.scottsdalecvb.com/about/index.cfm?action Source: http://en.wikipedia.org/wiki/Scottsdale%2C_Arizona
