From studying our rocks, we know that at different times over the past 2.8 billion years, mountains and volcanoes stood tall in central Wisconsin, a shallow sea covered much of the state, and glaciers plowed across the landscape. This poster helps students (4th grade and older) piece together our past.
Using a simplified bedrock map, a representative core sample, and a slice of earth, students will learn about the ages and kinds of rocks and fossils found beneath their feet.
The core sample features Milwaukee, the only place in the state where the full range of rock layers can be found.
