History

Mackinac Island was the third of three iron meteorites encountered by the rover on Meridiani Planum within a few hundred meters, the others being Shelter Island and Block Island.[2]

Mackinac Island may have fallen on Mars in the late Noachian period and is extensively weathered.[2][5]

gollark: Traits are like Haskell typeclasses or whatever-else interfaces, and very neat.
