Trivia: Michigan’s Isle Royale National Park holds what distinction?
Smallest national park
Newest national park
Only park to fully close in winter
Most glaciers of any park
The correct answer is Only park to fully close in winter
So why is this answer correct? : Michigan’s Isle Royale National Park covers the entirety of a 45-mile-long island in Lake Superior, the northernmost of the Great Lakes. Rugged and remote, it’s one of the least-visited U.S. national parks. One reason may be that the island fully closes every year from November 1 to April 15 — the only national park to do so — as the frigid conditions of Lake Superior make it too dangerous for visitors.
