Wonders of America: Missing Island Superlatives
June 17th, 2006The US Postal Service has issued 40 stamps sure to excite geographical obsessives, the “Wonders of America“:

Yet I guess you can’t please anyone; people have many complaints of omission (and suggestions); mine is obvious — there is not a single real island superlative.
A few come close:
- “Highest sea cliffs” is credited to Moloka’i (Molokai).
- “Deepest lake” shows Wizard Island in Crater Lake, Oregon.
- “Most active volcano” is Kilauea, on Hawaii.
- “Longest span” shows the Verrezano-Narrows Bridge between Long Island and Staten Island, New York.
- “Longest river system” appears to show one or more islands in the Mississippi.
- “Longest reef” is “off the Florida Keys.”
For the record, here are some American island superlatives:
- Largest island — The largest island of the United States is Hawaii, at 4,021 sq mi / 10,414 sq km, and still growing slowly. The largest (and longest) island of the lower 48 states is Long Island.
- Largest lake island — The largest lake island in the United States is Isle Royale, in Lake Superior, Michigan, at 209 sq mi / 541 sq km.
- Largest volcanic island — The largest volcanic island in the United States is Hawaii, at 4,021 sq mi / 10,414 sq km, and still growing slowly.
