The Ice Age Trail is within the Kettle Moraine for most of Waukesha County but does occasionally veer to the west onto an outwash plain where small areas of the Niagara Escarpment protrude from the soil. The Ice Age Trail crosses major glacial meltwater spillways near the villages of Wales and Hartland. Many types of glacial formations can be seen along the Trail such as kettles, erratics, eskers, drained lake plains, drumlins and kames. Vegetation includes oak forest, oak openings and wet and dry prairie. Seasonal wildflowers punctuate all these areas. The Trail highlights area city and county parks, multi-use recreation trails and the Kettle Moraine StateForest’s Lapham Peak Unit and Southern Unit.
