Ground Water Plaza
Even in the Land of 10,000 Lakes, most Minnesotans depend on ground water for their drinking water. Far more water exists underground in the pore spaces in sediments and rocks than in Minnesota's lakes, rivers, and wetlands. But how does water exist underground?
At the Ground Water Plaza, visitors can fill buckets with pristine water from the Science Museum's 300-foot-deep artesian well, and pour the water over samples of bedrock and sediment found beneath the Twin Cities—rock formations that are important sources of ground water. How can water move through seemingly solid rock? Find out for yourself as you explore these exhibits.
