Mastodon Township, Michigan

Mastodon Township is a civil township of Iron County in the U.S. state of Michigan. As of the 2000 census, the township population was 668, and by 2020 its population was 576.

Mastodon was so named from the fact mastodon bones were discovered when sinking a mine shaft.

Mastodon may have also been named for the size of the large, iron ore body which was struck at the mine site; as "Mastodon" at that time, being a relatively new discovery, was also being used as a slang adjective, meaning large/huge.
