Overview:

Researchers recently surveyed the bottom of Lake Michigan after spotting strange circles on the lakebed in 2022, and new observations show the circles are craters.

About Lake Michigan:

  • It is the third largest of the five Great Lakes of North America and the only one lyingwholly within the United States.
  • It is the fourth largest freshwater lake and the fifth largest lake in the world ranked by surface area.
  • The lake is 321 miles (517 km) long (north to south); it has a maximum width of 118 miles (190 km).
  • Drainage basin area: 45,600 square mi (118,095 square km)
  • Lake Michigan is connected directly to Lake Huron, into which it drains, through the broad Straits of Mackinac.
    • This hydrologic connection through the Straits keeps the water levels of the two lakes in equilibrium, causing them to behave in many ways as though they are one lake.
  • Water flows into Lake Michigan from several rivers in the 45,600 square mile Lake Michigan drainage basin, including the Fox-Wolf, the Grand, the St. Joseph, and the Kalamazoo rivers, among others. 
  • The lake boasts a variety of natural habitats, including tallgrass prairies, wide savannas, and the world’s largest freshwater sand dunes.
  • It hosts a wealth of plant and animal species, many of which are rare or endangered (such as the Hine’s Emerald Dragonfly and the Dwarf Lake Iris).

Q1: What is a Crater?

A crater is a bowl-shaped depression, or hollowed-out area, produced by the impact of a meteorite, volcanic activity, or an explosion. Craters produced by the collision of a meteorite with Earth (or another planet or moon) are called impact craters.
