Linn County in eastern Iowa combines the large Cedar Rapids-Marion urban area with a deeply dissected landscape of river valleys, creeks, and upland ridges. I-380 runs north through Cedar Rapids toward Hiawatha and Robins, U.S. 151 connects Marion with Springville, and U.S. 30 crosses the southern part of the county toward Mount Vernon. U.S. 218 provides a southwest reference near Fairfax, while Iowa 13 and Iowa 1 help locate the eastern and southeastern road network. The terrain-and-water map adds Cedar River through the urban core, Wapsipinicon River in the northeast, and several major creeks. This page explains the supplied county, city, terrain-and-water, and elevation maps, and high-resolution JPG versions can be downloaded in a ZIP near the end of the article. High-resolution map files are available for download in the section below.
The easiest way to orient the county is to begin with Cedar Rapids and Marion, then move north to Hiawatha and Robins. Fairfax anchors the southwest and Mount Vernon provides a southeastern reference. The elevation map shows a broad low corridor along Cedar River through the central and southwestern county, while much higher and more deeply dissected terrain dominates the northeast and east.

Cedar Rapids and I-380 organize the main urban corridor
Cedar Rapids is the strongest first landmark on the general county map. I-380 runs north-south through the city and continues toward Hiawatha and Robins. U.S. 30 crosses the southern side of the urban area before continuing east toward Bertram and Mount Vernon. Iowa 100 and Iowa 94 provide additional references around the western side.
Marion is directly east of Cedar Rapids and lies near U.S. 151 and Iowa 13. Springville is farther east along the U.S. 151 corridor, while Center Point provides a northwestern reference. Fairfax lies southwest of Cedar Rapids, Ely to the south, and Central City farther northeast. The map is intended for county-scale orientation rather than live navigation, so current closures, construction, and exact access should be checked with current transportation information.
The road network is most concentrated around Cedar Rapids and Marion and becomes more open toward the rural north and east. The water network follows a very different geometry, with Cedar River and the major creeks cutting across the straight road grid. Comparing both layers makes the transition from urban corridor to rural ridge country easier to understand.
Cedar Rapids, Marion, and Hiawatha dominate the city pattern
The city map ranks Cedar Rapids first with a mapped population of 137,264. Marion is second at 41,896 and Hiawatha third at 7,206. Mount Vernon is fourth at 4,513, Robins fifth at 3,332, and Fairfax sixth at 2,900. The three largest highlighted communities form a close western and central cluster, while Mount Vernon and Fairfax provide more distant references on the southeastern and southwestern sides.
Marion lies directly east of Cedar Rapids, while Hiawatha and Robins extend the urban area northward. Fairfax anchors the southwest and Mount Vernon the southeast. Neighboring counties shown around the city map include Buchanan, Jones, Cedar, Iowa, Benton, Delaware, and Johnson, placing Linn County within eastern Iowa.
The city distribution becomes even more informative when compared with relief. Cedar Rapids sits directly along the low Cedar River corridor, while the terrain east of Marion and toward Mount Vernon rises into a more deeply dissected ridge system. Hiawatha and Robins are close to tributary valleys north of the urban core, and Fairfax lies near the broader western river lowlands.
Cedar River forms the central low corridor through Cedar Rapids
Cedar River is the dominant waterway on the terrain-and-water map. It enters from the western side, passes through the Cedar Rapids area, and continues southeast through a broad low corridor. West Fork Cedar River approaches from the west, while Cedar Lake and Robbins Lake provide fixed water references around the urban area. On the elevation map, the main river corridor appears as extensive dark-green low ground.
Big Lewis Lake and Goose Pond are labeled in the northwest, with Horseshoe Lake and Mud Lake farther south. Jones Park Lagoon appears close to the Cedar Rapids urban core. These smaller water bodies help locate the broad river lowlands and show that the western side includes a mixture of channels, ponds, and tributary valleys rather than a single river course.
This sheet is intended for geographic reference rather than flood forecasting, current water levels, navigation, parcel boundaries, or legal water limits. Its main value is showing how the large river corridor and smaller tributaries fit around the county’s urban and rural areas.
Wapsipinicon River and eastern creeks divide the northeastern uplands
Wapsipinicon River is the major northeastern waterway and follows a winding southeastward valley through the higher ridge country. Maine Creek forms another long tributary valley farther east. On the elevation sheet, these lower channels appear as green corridors cut deeply into the brown and dark-orange uplands.
Dry Creek crosses the central-northern interior, while Indian Creek and Big Creek create long lower routes east and northeast of Cedar Rapids. These streams are much smaller than Cedar River, but they strongly influence local relief by separating short ridges around Marion and the surrounding countryside.
Central City provides a useful reference for the Wapsipinicon side, while Springville helps locate the Big Creek and eastern-upland area. Center Point is a convenient anchor for the northwest. Pairing those towns with the drainage network makes the complex ridge-and-valley pattern easier to remember.
Elevation ranges from 155 to 334 meters
The supplied elevation map shows an actual county range of about 155 to 334 meters, with a mean elevation of 259 meters. The lowest dark-green terrain follows Cedar River across the west-central, central, and southeastern parts of the county. Higher brown and dark-orange terrain is concentrated across much of the northeast and east. The mapped difference exceeds 170 meters, producing one of the clearest lowland-versus-ridge contrasts in the supplied county series.
The northeastern high ground is not a single smooth plateau. Wapsipinicon River, Maine Creek, and many smaller tributaries carve deep valleys into it. Dry Creek creates another lower corridor through the central-northern interior, while the broad Cedar River lowland spreads across the Cedar Rapids side. East of Marion and toward Mount Vernon, short ridges and creek valleys alternate rapidly.
The elevation colors are designed for broad terrain comparison rather than survey-grade measurement. Exact parcel elevation, road grade, engineering design, or construction work requires original elevation data or professional surveying. For general map reading, the key pattern is the broad Cedar River lowland surrounded by much more strongly dissected uplands.
Urban corridors and river valleys overlap across Linn County
Linn County is easiest to understand by combining its large urban corridor with the underlying drainage network. Cedar Rapids, Marion, Hiawatha, and Robins are linked by I-380, U.S. 151, and major local roads, yet the same area is divided by Cedar River, Indian Creek, and other tributary valleys. The road map emphasizes movement between communities, while the terrain map reveals the low corridors and ridges beneath that network.
Fairfax is useful for the southwestern river lowland, Mount Vernon for the southeastern ridge country, Central City for the northeastern Wapsipinicon side, and Springville for the eastern U.S. 151 corridor. Comparing the same places across the county, city, water, and elevation maps makes the county’s structure much easier to understand.
Choose the Linn County map that fits the task
Use the general county map when you need towns and numbered roads in one view. It is the quickest way to compare Cedar Rapids, Marion, Hiawatha, Robins, Fairfax, and Mount Vernon with I-380, U.S. 151, U.S. 30, U.S. 218, Iowa 13, and Iowa 1. The city map is better when the goal is to compare the six highlighted communities and the population ranking shown on the supplied graphic.
The terrain-and-water map is best for Cedar River, Wapsipinicon River, West Fork Cedar River, Dry Creek, Indian Creek, Big Creek, and the mapped lakes and ponds. The elevation map adds the 155–334 m range and makes the low central-southwestern river corridor and higher northeastern-eastern ridges immediately visible.
