Download four high-resolution JPG maps of Marion County, Illinois, in one ZIP from this page, then use the article maps to compare Salem, Centralia, Kinmundy, major roads, waterways, and elevation. Salem sits near the middle of the county, Centralia is on the southwestern edge, and Kinmundy is well to the northeast. The maps also show the East Fork Kaskaskia River, North Fork, Skillet Fork, several reservoirs and lakes, and a terrain range of roughly 129 to 199 meters.
Marion County is easiest to understand by using Salem as the central reference point. US 50 crosses east-west through Salem, Odin, Sandoval, and Iuka, while I-57 and Route 37 form a strong north-south corridor toward Alma and Kinmundy. Route 51 connects Sandoval with Central City and Centralia farther south. The water and elevation maps add another layer by showing how broad hills in the north-central interior are cut by lower creek and river valleys on both sides.
Table of Contents
Salem anchors the county’s east-west and north-south road pattern
The county map makes Salem the clearest starting point. US 50 runs through the city and continues west toward Odin and Sandoval, then east toward Iuka and the county line. Near Sandoval, Route 51 turns south toward Central City and Centralia. Route 161 crosses the southwestern part of the county around the Centralia area. This creates a useful sequence of places along the western and central road network without making Salem the only transportation center.
North-south travel is dominated by I-57 and Route 37 through the middle of the county. Both pass the Salem area and continue north toward Alma and Kinmundy, with I-57 forming the stronger long-distance corridor. Patoka and Vernon are separated in the northwest and sit away from the I-57 line, while Kell is far to the southeast. The settlement pattern therefore spreads across several different road systems instead of forming one continuous strip.
Centralia and Central City sit close together along the southwestern county edge, where the developed area approaches the boundary. Sandoval is farther north where Route 51 and US 50 meet, making it an important western reference point even though it is much smaller than Centralia or Salem. The map is intended for general geographic orientation rather than live navigation, so current road conditions, travel times, and turn-by-turn directions should still be checked with a dedicated travel service.
Six highlighted cities stretch from Centralia to Kinmundy
The ranked city map simplifies the county to six highlighted communities. Its index lists Centralia at 11,856, Salem at 7,236, Central City at 1,081, Sandoval at 1,004, Odin at 972, and Kinmundy at 803. Centralia is the largest highlighted city but sits at the southwestern edge rather than in the center. Salem is smaller but occupies the central location, which makes the two cities useful for different kinds of map reading.
Central City sits immediately north of Centralia, so those two places form a close southwestern pair. Sandoval is farther north, and Odin lies between the Sandoval side of the county and Salem. Kinmundy is separated from all of them in the northeast. The ranked view therefore reveals several distinct location groups: the Centralia-Central City area, the Sandoval-Odin corridor, central Salem, and northeastern Kinmundy.
The general county map adds smaller places such as Patoka, Vernon, Alma, Iuka, and Kell, so the two maps work best together. Find Kinmundy on the city map and then return to the road map to see its relationship to I-57. Do the same with Centralia and the Route 51-Route 161 area. This approach keeps the ranked city view readable while still preserving the broader network of smaller communities and roads.
East Fork Kaskaskia River, North Fork, reservoirs, and eastern streams
The terrain and water map is dominated in the north and northwest by the East Fork Kaskaskia River and North Fork. The two named waterways run across broad low corridors before the East Fork continues toward the central-northern part of the county. Their valleys are easy to compare with the elevation map because the river courses line up with long green lowlands cut into the surrounding hills.
A cluster of named lakes and reservoirs appears around Salem and the western half of the county. Salem Reservoir and Lake Wood are close to one another near the center, with Hecks Lake farther south. Lake Centralia and Raccoon Creek Reservoir lie in the southwest, while Raccoon Creek and Turkey Creek cross nearby. Prairie Creek occupies the west-central area, and Crooked Creek runs across the lower central part of the county.
The eastern side has a separate drainage pattern. Dums Creek is labeled across the east-central part of the county, and Skillet Fork follows a long north-south course near the eastern boundary. Forbes Lake provides another clear eastern landmark. The map is a geographic reference rather than a flood-risk product, legal water-boundary map, navigation chart, or drainage-engineering document.
A 129–199 m landscape with broad north-central high ground
The elevation map reports an actual range of about 129 to 199 meters and a mean near 163 meters. The broadest brown and tan high ground occupies the north-central interior, where rolling hills rise above the lower drainage corridors. To the west and northwest, the East Fork Kaskaskia River and North Fork have carved long green valleys. Similar low terrain appears along the eastern side around Skillet Fork and its tributaries.
Salem sits closer to the middle elevations than to the county’s highest ground. Moving north from the Salem area, the terrain becomes more strongly shaded and reaches the higher hills in the north-central section. The south is generally gentler, but several compact higher ridges appear again toward the south-central and southern edge. Marion County therefore does not follow one simple north-to-south slope; its shape is better understood as high interior ridges separated by branching stream valleys.
The elevation surface is generalized for county-scale comparison. It should not be treated as survey-grade height, parcel elevation, construction data, or an engineering model. For ordinary map reading, however, it makes the water map much easier to interpret because East Fork Kaskaskia River, Crooked Creek, Skillet Fork, and other streams follow the lower green corridors between higher ridges.
Following Salem, Centralia, and Kinmundy across the four views
Start with the county map when roads, boundaries, and all labeled settlements matter most. Use the ranked city map when the main question is how Centralia, Salem, Central City, Sandoval, Odin, and Kinmundy are distributed. The terrain and water map is the best choice for the East Fork Kaskaskia River, Salem Reservoir, Lake Centralia, Crooked Creek, and Skillet Fork, while the elevation map explains the contrast between the higher interior and the lower drainage corridors.
Following one place across several maps adds more local context. Salem can be located on the county map at the meeting of US 50 and the north-south highway corridor, then compared with Salem Reservoir and Lake Wood on the water map. Kinmundy is easy to find in the northeast on the city map and then relate to I-57 on the general map. Centralia is the largest ranked city, and the county map adds Central City plus Routes 51 and 161 around the southwestern urban area.
Frequently Asked Questions
Which map is best for comparing Salem, Centralia, and Kinmundy?
The ranked city map is the quickest comparison. Salem is near the center, Centralia is on the southwestern edge, and Kinmundy is well to the northeast. Central City is immediately north of Centralia, while Sandoval and Odin occupy the western half between the Centralia area and Salem. Switch to the county map when you also want to see US 50, I-57, Route 51, and Route 161.
Why does the north-central part of Marion County look higher on the elevation map?
The broadest high ground appears in the north-central interior, while the East Fork Kaskaskia River and North Fork cut lower valleys through the west and northwest. Skillet Fork and smaller streams create additional low corridors on the eastern side. Comparing the water and elevation maps makes the relationship clear because the named streams line up with the green valleys between the higher tan and brown ridges.
What files are included in the downloadable ZIP?
