Cass County in west-central Illinois changes markedly from the low river country around Beardstown to the rolling interior east of Virginia. Beardstown sits on the western side near the Illinois River corridor, while Virginia occupies a more central inland position. Chandlerville is farther northeast, Ashland is near the eastern edge, and Arenzville lies toward the southern boundary. The water and elevation maps show that these settlements are spread across two very different landscapes: broad western floodplain and higher, more dissected ground to the east and southeast.
This Cass County Illinois Map page combines a detailed county overview, a ranked-city distribution map, a terrain-and-water map, and an elevation map. You can download high-resolution JPG versions of all four supplied maps together in one ZIP file for printing, classroom work, presentations, or closer viewing. The maps are designed for county-scale orientation rather than live traffic, parcel boundaries, flood decisions, navigation, or survey-grade elevation.
Cass County’s official website describes the county as a small rural county along both the Illinois and Sangamon rivers, directly west of Springfield. The Illinois State Archives identifies Virginia as the current county seat. Those facts match the structure visible in the supplied maps: Beardstown is tied closely to the western river lowlands, while Virginia sits inland among roads and creek valleys. The sections below use those two places as anchors for the county’s towns, drainage features, and elevation change.
Table of Contents
Beardstown and Virginia set the main west-to-east reference
The county overview is easiest to enter from the west at Beardstown. The city sits close to the large river boundary, and the Beardstown Police Department label provides a clear local reference. Roads leave Beardstown toward the interior and eventually connect with the Virginia area. Around Virginia, Route 78 and several local routes divide toward the north and south, making the town a useful inland reference point even though Beardstown is visually more prominent on the river side.
Chandlerville appears northeast of Virginia, while Ashland lies near the eastern edge of the county. Arenzville is close to the southern boundary and east of Beardstown. Outside the county, labels such as Rushville, Browning, Oakford, Literberry, and Meredosia help establish the surrounding regional directions. Cass County therefore does not read as one compact town cluster; its principal places are spaced across a long west-to-east landscape.
The road pattern also shows how the county’s broad shape is organized. Routes from Beardstown head east across low country, while Virginia connects northward toward Chandlerville and southward through the interior. Ashland sits at the far eastern side, where roads continue toward neighboring Mason, Menard, and Sangamon counties. The overview works well for general orientation, but it does not provide current closures, construction, lane details, exact parcel lines, or private-access rights.
Virginia is the current county seat
The Illinois State Archives records Cass County as established in 1837 and shows that the county seat changed several times between Beardstown and Virginia. Virginia has served as the county seat since 1867. That history is useful when reading the map because Beardstown may appear to be the stronger river city, while Virginia is the present administrative center.
Five ranked places stretch from the river side to the east
The city-distribution map removes most road detail and emphasizes five places. Beardstown is ranked number 1, Virginia number 2, Ashland number 3, Chandlerville number 4, and Arenzville number 5. The printed CITY INDEX lists values of 6,169 for Beardstown, 1,543 for Virginia, 999 for Ashland, 534 for Chandlerville, and 342 for Arenzville.
The graphic does not display a census year or statistical date beside those values, so this article does not present them as current population counts. They are treated only as figures printed on the supplied city map. The spatial pattern is clear without making a population claim: Beardstown is on the west, Virginia is central, Ashland marks the east, Chandlerville the northeast, and Arenzville the south.
The simplified positions are useful because they remove the dense creek network that can make the full overview look busy. Beardstown is clearly separated on the western side, while Virginia acts as the central inland point. Ashland lies near the far eastern edge, and Chandlerville and Arenzville provide northern and southern references. Together, the five labels create an easy mental frame for the rest of the maps.
The CITY INDEX is map data, not a current census table
If a report requires current official population figures, use a dated U.S. Census Bureau source. The supplied map does not identify the year behind its index. On this page, the figures are used only to describe the supplied ranking and the relative prominence and location of the five labeled communities.
Sangamon River backwaters and creeks define the low country
The terrain-and-water map changes the emphasis from roads to drainage. Little Sangamon River winds through the northwestern side, while the Sangamon River is labeled along the northern and northeastern part of the county. Collis Pond, Clear Lake, and Cottonwood Lake appear within low floodplain country, and Mathew Bay and Patterson Bay are labeled just beyond the northern boundary. The concentration of water features makes the northwestern landscape look very different from the drier, higher interior.
Farther inland, Middle Creek runs down the eastern side, Panther Creek crosses the east-central area, and Job’s Creek occupies the middle of the county. Clear Creek, Prairie Creek, and Indian Creek form long winding channels across the southern and southwestern half. These waterways occupy lower corridors cut into the higher terrain and help explain why the elevation map shows so many narrow green valleys on the eastern side.
The Illinois Department of Natural Resources describes Sanganois State Fish & Wildlife Area, which spans parts of Cass, Mason, and Schuyler counties, as a bottomland complex of sloughs, backwater lakes, timbered ponds, and floodplain forest. That official description provides useful context for the many water bodies visible around Cass County’s northwestern lowlands. It also matches the county government’s broader description of Cass County as lying along both the Illinois and Sangamon rivers.
The water map is not a flood or navigation product
The map shows the locations of rivers, creeks, ponds, lakes, bays, and surrounding terrain. It does not provide flood-hazard zones, live river stages, water depth, navigable channels, levee conditions, water rights, or legal access. Current USGS, Illinois DNR, and other responsible agency information should be used for safety, boating, flood, or regulatory decisions.
Elevation rises from the western floodplain to the eastern uplands
The elevation map makes Cass County’s west-to-east contrast especially clear. The Beardstown side and much of the northwestern floodplain are dark green, showing broad low ground. Moving east, the colors shift through lighter green and yellow. East and southeast of Virginia, orange and brown ridges become widespread, while creek valleys remain green as they cut through the higher terrain.
The map reports an actual countywide elevation range of about 127 to 207 meters and a mean of about 164 meters. Its color legend uses bands from roughly 130 to 195 meters, while the separate “Actual” line records the wider minimum and maximum in the underlying county dataset. Those endpoints describe Cass County as a whole; they are not exact elevations for Beardstown, Virginia, Ashland, Chandlerville, or any specific property.
Reading the water and elevation maps together makes the valley pattern easy to recognize. The northwestern lakes and Sangamon-related waterways sit within broad low green areas, while Panther Creek, Job’s Creek, and Middle Creek occupy narrow lower corridors through the eastern uplands. The sharp transition east of the Beardstown lowlands explains why the same county contains both expansive floodplain country and deeply dissected rolling terrain.
127 to 207 meters is a countywide range
Do not assign the low or high endpoint directly to a named town. Exact elevation for a building site, road grade, drainage design, levee, bridge, or parcel requires location-specific source data or a professional survey. This map is designed for broad county comparison rather than precise engineering measurement.
Choosing the Cass County map that fits the question
Use the county overview when you need Beardstown, Virginia, Chandlerville, Ashland, Arenzville, numbered roads, county boundaries, and streams in one image. The ranked-city map is better for quickly comparing the five labeled communities. Choose the terrain-and-water map for the Sangamon River system, Panther Creek, Job’s Creek, Clear Creek, and the floodplain lakes. The elevation map is the clearest option for comparing the low western river country with the higher eastern uplands.
A practical sequence is to begin with Beardstown and Virginia on the overview, then trace the main routes toward Chandlerville and Ashland. Next, simplify the settlement pattern with the city map. Move to the water map to find the Sangamon rivers, Panther Creek, and the northwestern backwater features, then finish with elevation to see how those waterways occupy lower ground below the rolling eastern terrain.
Each map has a defined purpose. The overview is not a live-traffic or parcel product, the CITY INDEX is not presented as a current census table, the water map does not assess flood or navigation conditions, and the elevation surface is not survey-grade. Within those limits, the set works well for printed reference sheets, teaching, presentations, county orientation, and trip-planning context.
Frequently Asked Questions
What is the current county seat of Cass County, Illinois?
Virginia is the current county seat. The Illinois State Archives records several historical changes between Beardstown and Virginia, with Virginia serving as the county seat from 1867 to the present.
Are the CITY INDEX values current population counts?
This page does not treat them as current population figures because the supplied map does not show a census year or statistical date beside the index. Use a dated U.S. Census Bureau source when an official current population figure is required.
Does 127 to 207 meters give Beardstown’s or Virginia’s elevation?
No. The elevation map identifies 127–207 m as the actual range across the Cass County dataset and gives a mean of about 164 m. Exact elevation for Beardstown, Virginia, or any specific road, property, or structure requires point-specific elevation or survey data.
