On October 10, 1767, Charles Mason and Jeremiah Dixon complete their survey of the boundary between the colonies of Pennsylvania and Maryland as well as areas that would eventually become the states of Delaware and West Virginia.

On October 10, 1877, the U.S. Army holds a West Point funeral with full military honors for Lieutenant-Colonel George Armstrong Custer. Killed the previous year in Montana by Sioux and Cheyenne Indians at the Battle of the Little Big Horn, Custer’s body had been returned to the East for burial on the grounds of the U.S. Military Academy at West Point, New York, where Custer had graduated in 1861—at the bottom of his class.

On October 10, 1987, the song “Here I Go Again” by English hard-rock group Whitesnake tops the Billboard pop singles chart in the United States. Today, what most people remember about the song is its saucy video: The actress Tawny Kitaen spends a great deal of it in a white negligee, writhing and cartwheeling across the hoods of two Jaguars parked next to one another. It is one of the most iconic music videos of the 1980s, and it features two of the most famous cars in pop-culture history.
