The Gila and Salt River Meridian intersects the initial point on the south side of the Gila River, opposite the mouth of Salt River, at latitude 33° 22′ 37.82733″ north, longitude 112° 18′ 21.99931″ west from Greenwich based on NAD 83, and governs the surveys in the territory of Arizona. The current declination for the initial point is 12° east. It is located on Monument Hill, an easily visible hill just south of the confluence of the Gila and Salt Rivers, in Avondale, Arizona, about 14 miles (23 kilometers) southwest of downtown Phoenix. The original marker was set in 1851 by John R. Bartlett. In 1934, the U.S. Coast and Geodetic Survey set triangulation station "INITIAL" approximately 15 feet from the initial point. Ty White, Associate Cadastral Engineer for the U.S. Bureau of Land Management (BLM), re-monumented the initial point on December 1, 1944. On April 24,1962, the monument was re-established by Leonard W. Murphy, based on the Ty White's field notes, because the previous monument had been vandalized. On April 26, 1984, Paul L. Reeves and John P. Bennet re-monumented the original corner. On February 19, 2006, the initial point was again re-monumented due to deterioration of the 1985 plaque. This re-monumentation was performed by staff from the BLM, members of the Arizona Professional Surveyors Society, and students at Phoenix College. The initial point was added to the National Register of Historic Places (listing #02001137) as of October 15, 2002. The plaque for that listing was installed as part of the 2006 re-monumenting. For the 1984/2006 marker, handheld GPS units give a reading of 33° 22.631′ N latitude and 112° 18.366′ W longitude due to the specific geoid used. The angle between the 1984/2006 marker and the 1931 marker is at an azimuth bearing of 292°, aka 68° west of due north. The location is immediately east of Phoenix Raceway (formerly Phoenix International Raceway) and the western side of Monument Hill is terraced for low-priced race viewing.

The Salt River (Spanish: Río Salado, O'odham [Pima]: Onk Akimel, Yavapai: Hakanyacha or Hakathi:, Maricopa language: Va Shly'ay) is a river in Gila and Maricopa counties in Arizona, United States, that is the largest tributary of the Gila River. The river is about 200 miles (320 km) long. Its drainage basin covers about 13,700 square miles (35,000 km2). The longest of the Salt River's many tributaries is the 195-mile (314 km) Verde River. The Salt's headwaters tributaries, the Black River and East Fork, increase the river's total length to about 300 miles (480 km). The name Salt River comes from the river's course over large salt deposits shortly after the merging of the White and Black Rivers.

The Salt River Valley is an extensive valley on the Salt River in central Arizona, which contains the Phoenix Metropolitan Area. Although this geographic term still identifies the area, the name "Valley of the Sun" popularly replaced the usage starting in the early 1930s for purposes of boosterism. A common dust for testing air filter efficiency was derived from top soil dust from the Salt River Valley, referred to as Arizona Dust. The dust was found to include small abrasive particles.

The Agua Fria River (Spanish for "cold water") is a 120-mile (190 km) long intermittent stream which flows generally south from 20 miles (32 km) east-northeast of Prescott in the U.S. state of Arizona. Prescott draws much of its municipal water supply from the upper Agua Fria watershed. The Agua Fria runs through the Agua Fria National Monument. The river then flows through a small canyon called "Black Canyon" into Lake Pleasant, a popular recreation area near Peoria, Arizona. (There is a large "Black Canyon" on the Colorado River along the Arizona–Nevada border.) During rainy weather and at times when water is flowing in the intermittent Agua Fria River, it discharges into the Gila River, which also only flows during wet periods of the year. The Central Arizona Water Conservation District of the Central Arizona Project operates the Agua Fria Recharge Project, which is about 4 miles (6.4 km) south of the New Waddell Dam. It serves to recharge underground aquifers in this area, and ends at Lake Pleasant, Phoenix.
