Scottsdale (O'odham: Vaṣai S-vaṣonĭ; Yaqui: Eskatel) is a city in the eastern part of Maricopa County, Arizona, United States, part of the Greater Phoenix Area. Named Scottsdale in 1894 after its founder Winfield Scott, a retired U.S. Army chaplain, the city was incorporated in 1951 with a population of 2,000. The 2015 population of the city was estimated to be 236,839 according to the U.S. Census Bureau. The New York Times described downtown Scottsdale as "a desert version of Miami's South Beach" and as having "plenty of late night partying and a buzzing hotel scene." Its slogan is "The West's Most Western Town."
Scottsdale, 31 miles long and 11.4 miles wide at its widest point, shares boundaries with many other municipalities and entities. On the west, Scottsdale is bordered by Phoenix, Paradise Valley and unincorporated Maricopa County land. Carefree is located along the western boundary, as well as sharing Scottsdale's northern boundary with the Tonto National Forest. To the south Scottsdale is bordered by Tempe. The southern boundary is also occupied by the Salt River Pima-Maricopa Indian Community, which extends along the eastern boundary, which also borders Fountain Hills, the McDowell Mountain Regional Park and more unincorporated Maricopa County land.
The area which would include what would become Scottsdale was originally inhabited by the Hohokam, from approximately 300 BC to 1450 AD. This ancient civilization farmed the area and developed a complex network of canals for irrigation which was unsurpassed in pre-Columbian North America. At its peak, the canals stretched over 250 miles, many of which built remains extant today, some having been renovated and put back into use in the 20th century. Under still-mysterious circumstances, the Hohokam disappeared around 1450 or 1500, the most likely theory having to do with a prolonged drought.
