Pinal County covers a broad part of south-central Arizona between the Phoenix metropolitan area and Tucson. The supplied Pinal County Map set shows a county with several distinct geographic areas: Maricopa and Casa Grande in the west and southwest, Florence and Coolidge near the center, Apache Junction in the northern extension, and a more rugged eastern side around Superior, Kearny, Winkelman, and Mammoth. Separate water and elevation views add the Gila, Santa Cruz, and San Pedro rivers, numerous desert washes, and the large rise from low western plains to eastern mountains. The WebP maps on this page are quick previews, and you can download the four matching high-resolution JPG files in one ZIP for printing or closer study.
Florence and Casa Grande make practical starting points for orientation. Florence sits near the middle of the county, while Casa Grande and Coolidge lie to the southwest and Eloy farther south. Interstate 10 cuts diagonally across the western and southern portion, and US 60 crosses the northern area from Apache Junction toward Superior. In the east, Routes 177 and 77 connect the Superior, Kearny, Winkelman, and Mammoth side. Following those roads first makes it easier to understand why the county’s western urban areas and eastern mountain communities appear so different on the same map.

Florence and Casa Grande anchor the central road network
The general county map places Florence close to the center, with Casa Grande and Coolidge southwest of it and Eloy farther south. Maricopa is separated to the west and is connected northward by Route 347. Interstate 10 passes through the broader Casa Grande-Eloy area, while Route 79 runs south from the Florence side. Rather than forming one continuous strip of development, the cities are spread across broad lowland areas linked by several major routes, so reading the place names and road lines together gives a much clearer picture than either layer would alone.
The northern part has a different arrangement. Queen Creek and San Tan Valley sit near the northwest side of the upper section, and Apache Junction appears farther north where US 60 enters the county. US 60 continues east toward Superior. From Superior, Route 177 bends southeast toward Kearny and Winkelman, and Route 77 continues south toward Mammoth and Saddlebrooke. These eastern routes pass through visibly rougher terrain than the long open segments around I-10, which helps explain the more winding road pattern.
The boundary itself is also useful for orientation. The northwest edge steps around neighboring Maricopa County, while the northeast narrows toward higher terrain. Farther east, the outline pulls inward and then projects outward again around the Winkelman side, so the county is far from a simple rectangle. Keeping that shape in mind helps when comparing maps because places such as Superior and Mammoth occupy very different parts of the county from Maricopa and Casa Grande.
The ranked city map separates the main population centers from smaller places
The city map highlights six ranked places. Its printed index lists Maricopa at 67,163, Casa Grande at 60,905, Apache Junction at 41,058, Florence at 25,570, Eloy at 17,433, and Coolidge at 16,636. These numbers are best treated as the values embedded in the supplied map rather than as a promise of the newest population estimates. Their main purpose here is to show which communities were selected for the ranked city layer.
Maricopa appears on the western side, while Casa Grande, Eloy, Florence, and Coolidge form a broader central and southwestern group. Apache Junction stands apart in the northern extension. That distribution makes it clear that Pinal County does not have one single city cluster. The general map also names communities such as Superior and Mammoth that do not appear among the six ranked city markers, which is another reason to use the city map for selected population centers and the general map for broader geographic context.
This version works well for a presentation, worksheet, or quick city-location comparison because the labels are larger and the road network is reduced. It is not the best choice for explaining travel connections. For that, pair it with the general county map, where I-10, US 60, Route 79, Route 347, and the eastern Routes 177 and 77 show how the selected places relate to the larger transportation pattern.
The Gila River crosses the county while other channels feed the lowlands
The terrain-and-water map gives the Gila River the clearest visual role. It crosses the county from the northwest-central side toward the east, with Little Gila River and North Side Canal labeled nearby. The western and central lowlands also contain named water features such as Lake of the Desert, Picacho Reservoir, and Paradise Lake. These features stand out because the road map emphasizes cities and highways, while the water map reveals how many drainage lines and constructed water channels cross the same broad plains.
Farther south, Santa Cruz River enters the county and runs near the Central Arizona Project Aqueduct and McClellan Wash. Big O Wash and Cottonwood Wash appear farther east across the central terrain. The eastern side has another major north-south reference in the San Pedro River, with Aravaipa Creek and Deer Creek nearby. That eastern drainage network lies within noticeably rougher relief, and many smaller blue tributary lines branch through the hills and valleys.
A blue line on this map does not mean that water is always flowing there. Features labeled as washes can be dry channels for long periods, and canals or aqueducts differ from natural rivers. The map is useful for locating drainage features and comparing them with terrain, but it does not report current streamflow, flood probability, water depth, or public access. Safety, flood, engineering, and development decisions should rely on current official sources designed for those purposes.
Elevation climbs sharply from western plains into the eastern high country
The elevation map reports an actual range of about 164 to 2,219 meters, with a mean of 711 meters. Green covers most of the western and southwestern county, indicating broad low-elevation plains around the Maricopa and Casa Grande side. Small isolated ridges rise above those plains, but the dominant pattern remains relatively low and open compared with the eastern half.
Higher terrain becomes much more prominent toward the east and northeast. Brown and tan colors spread across mountain blocks near the county’s eastern boundary, while additional ridges rise through the central-east and southeast. The San Pedro River corridor occupies a lower strip between higher terrain on either side, and parts of the Gila River corridor also follow lower ground. Comparing the water and elevation maps makes these relationships easy to see without needing technical terrain terminology.
The colors are meant for countywide comparison, not precise site measurement. Actual elevation can vary within one color band, and small ridges or drainage cuts may be simplified at this scale. The map is suitable for explaining broad high and low areas, but parcel-level elevation, construction, engineering, and survey work should use original USGS elevation data or professional measurements appropriate to the site.
Pick the map that matches the detail you need
Use the general county map when roads, communities, and the boundary all matter at once. The ranked city map is better when the task is simply to compare Maricopa, Casa Grande, Apache Junction, Florence, Eloy, and Coolidge. The terrain-and-water map is the clearest choice for the Gila, Santa Cruz, and San Pedro rivers and the many washes, while the elevation map shows the strong contrast between the low western plains and high eastern terrain. Keeping those subjects separate makes each image easier to read.
The WebP images in the article are optimized for quick viewing. For printing, presentations, or closer inspection of place and water labels, download the high-resolution JPG originals from the ZIP below. The archive contains four separate files matching the county, city, terrain-and-water, and elevation views. If a map needs to be cropped for a handout, keeping the county boundary, north arrow, and legend visible will make the result easier for another reader to understand.
Use specialized sources when the question goes beyond a reference map
The general map does not show every local street, building, parcel, or ownership boundary. Values printed in the ranked city index belong to the supplied map and should not automatically be treated as the latest population estimates. The water map does not provide flood risk or current flow, and the elevation map does not replace survey-grade data. Address research, property ownership, legal boundaries, construction, and hazard planning all require current authoritative sources for those tasks.
The official Pinal County website identifies county government contact information in Florence, which is consistent with Florence’s central administrative role on the supplied maps. U.S. Census Bureau TIGER/Line data provide geographic boundary resources, and USGS programs provide hydrography and elevation data. This page has a narrower purpose: helping visitors understand the supplied Pinal County maps quickly and obtain the matching map files without confusing a general reference map with a legal, engineering, or hazard product.
Frequently Asked Questions
Which Pinal County map is best for comparing Florence and Casa Grande?
The general county map is the best starting point because it shows both cities together with I-10, Route 79, Coolidge, Eloy, and surrounding roads. The city map gives a cleaner location comparison but removes much of the road detail.
Where are the Gila River and San Pedro River on the map set?
The terrain-and-water map is the clearest choice. The Gila River crosses the central part of the county, while the San Pedro River runs north-south on the eastern side. The same map also labels the Santa Cruz River, several washes, reservoirs, and the Central Arizona Project Aqueduct.
Can the 164–2,219 meter elevation range be used as an exact site elevation?
No. The displayed range is useful for comparing broad high and low areas across Pinal County. Exact elevation for a parcel, structure, road, or construction site should come from original elevation data or an appropriate professional survey.
