Michigan's ___ Royale National Park

ISLE

This Great Lakes archipelago shares its name with a small, isolated landmass.

This clue is asking for the missing word in the name of Michigan’s only national park, Isle Royale. The answer is "ISLE," which simply means a small island—fitting since the park is located on a large island in Lake Superior. There’s no wordplay here; it’s a straightforward fill-in-the-blank based on geography. If you’ve heard of the park or know Michigan’s landmarks, the answer comes naturally.
