* Moraines: These are hilly areas formed by the deposition of rock and sediment left behind by glaciers. Gurnee sits on the edge of the Valparaiso Moraine, a prominent glacial feature that extends across northern Indiana and Illinois.
* Outwash plains: These flat, sandy areas were formed by meltwater flowing from glaciers. You'll find some outwash plains in Gurnee, especially along the Des Plaines River.
* Lakebeds: The area was once covered by glacial Lake Chicago, which left behind flat, fertile soils. Much of Gurnee sits on these former lakebeds.
* Rivers and streams: The Des Plaines River flows through Gurnee, creating a significant riverine feature. There are also several smaller streams and tributaries in the area.
* Wetlands: Some areas of Gurnee contain wetlands, including marshes and swamps, which are important habitats for wildlife.
While Gurnee doesn't have dramatic mountains or canyons, its glacial landscape offers a variety of landforms that contribute to its unique character.
