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.

Delicate Arch
The world-famous Delicate Arch was formed by the movement of underground salt beds beneath overlying sandstone, in concert with surface events including water, ice, and erosion, which washed away or broke off the sandstone to create the arches and fins found throughout Arches National Park.
