Here's a picture my dad gave me today. It shows him in 1923 with a muskellunge he caught in the short channel between Lake Michigan and Portage Lake in Onekema, MI: a young Nick Adams. (Ernest Hemingway and my father were born in Oak Park, IL about 18 years apart. Like many Oak Park families before air conditioning, in their times the Hemingways and Sailers spent much of the summer in Michigan; the prevailing wind blows across the lake from Illinois to Michigan, being cooled as it goes, so the west coast of Michigan used to be a major summer resort for Chicagoans.)

A muskellunge is the largest fish of the pike family. Wikipedia informs us:

The name comes from the Ojibwa word maashkinoozhe, meaning "ugly pike."
