On Monument Hill, at 115th Avenue and Baseline Road in Avondale, sits the initial point of the Gila and Salt River Meridian, the survey mark that governs the land surveys of Arizona. Monument Hill is printed on this map, along with Phoenix Raceway right beside it, Historic Avondale, Agua Fria High School, Estrella Mountain Community College, the Avondale Aquatic Center and Alamar Park, from Country Villa out to Coldwater Springs, with the Gila River and the Roosevelt Canal crossing the city.
Avondale is in Maricopa County, on the west side of Phoenix.
KNOWOL made this map in 2026 and gave it the look of an old atlas. The shaded relief of Monument Hill comes from United States Geological Survey elevation data, and the streets were drawn from Census Bureau files. The Gila River crosses the southern part of the city, where the Agua Fria River joins it from the north, and Interstate 10 crosses the northern part. The city covers 47.9 square miles, and it’s bordered by Goodyear to the west, Litchfield Park to the north, and Phoenix and Tolleson to the east. Avondale had 89,334 people at the 2020 census, up from 35,883 in 2000.
Coldwater
William “Billy” G. Moore came to Arizona in the late 1860s and settled near the Agua Fria River in 1880. He named his settlement Coldwater, apparently for both the river and the water from a local spring. In the 1880s he set up the Coldwater Stage Station near the Agua Fria crossing, one of the earliest stage stations in the region, where travelers bound from Tucson to northern Arizona and California picked up supplies. A saloon and a general store followed. A post office opened in 1896 near the Avondale Ranch, and Moore was postmaster of the Coldwater post office from 1901 to 1905. In time the office took the name of the nearby ranch, and Coldwater gave way to Avondale. Coldwater Springs and Country Villa are printed on the map today.
Ranching, the railroad and cotton farming became the main businesses, and Western Avenue filled with the mix of styles typical of small western towns. Avondale was incorporated in December 1946. Historic Avondale is printed on the map. The town page says the Old Town area along Western Avenue keeps the historic business district and its room for small, independent businesses. A list of the city’s historic places includes the Avon Theater of 1947 and the Googie-style Burger Building of 1960, both on Western Avenue. Once a thinly settled farming community with fields of alfalfa and cotton, Avondale has become a major suburb of Phoenix.
The initial point
Monument Hill rises just south of where the Salt River meets the Gila, about 14 miles southwest of downtown Phoenix. The first marker was set there in 1851, and the point has been re-monumented many times since, most recently in 2006 by the Bureau of Land Management, the Arizona Professional Surveyors Society and students from Phoenix College. It was added to the National Register on October 15, 2002. The meridian’s page notes that the west side of the hill is terraced for low-priced seats to watch the races next door.

Around Avondale
Phoenix Raceway, a one-mile oval, opened in 1964 and holds NASCAR and IndyCar races; from 2020 to 2025 it hosted NASCAR’s championship race each November. A hillside seating area outside its first and second turns is called Rattlesnake Hill, after old stories of officials clearing out rattlesnakes and scorpions before races. Agua Fria High School graduated its first class in 1932 as Litchfield Park High School and moved to Avondale in 1956, taking its name from the river beside it. Randall McDaniel, who went on to the Pro Football Hall of Fame in 2009, was a sprinter there. Estrella Mountain Community College has taught at its Avondale campus since 1992.
Michael P. Anderson, a United States Air Force officer and NASA astronaut, went to third grade at Avondale Elementary School, and the school, built in 1937, was renamed in his honor. The Avondale Aquatic Center, Alamar Park and the Roosevelt Canal are printed on the map. Alamar Park is one of the city’s parks, on South El Mirage Road.
This Avondale map is a good addition to an office, library or den, and it can help teach children the geography and history of the area. It’s made for anyone who calls Avondale home, from Country Villa to Coldwater Springs, and KNOWOL created it in 2026 to show the city as it looks today.
