Approximately 50,000 computers remained outdoors on 15 acres for nearly a decade. The site has since been cleaned up.

Invasive Zebra Mussels
The zebra mussel (Dreissena polymorpha) is a small, non-native mussel originally found in Russia. In 1988, this animal was transported to North America in the ballast water of a transatlantic freighter and colonized parts of Lake St. Clair. In less than ten years, zebra mussels spread to all five Great Lakes.
