On this day in 2015, divers discovered Michigan’s underwater Stonehenge on the bed of Lake Michigan. The ring of stones, resembling the British Isles' Stonehenge, features carvings of animals like mastodons and is believed to date back to the last ice age, around 14,000 years ago. Also today in 1857, Michigan’s first Black legislator, William Ferguson, was born in Detroit. After winning a racial discrimination case, Ferguson became prominent and was elected as Michigan’s first Black Representative in the 1890s. His portrait was placed in the Michigan State Capitol in 2018.
