Philippine island qualifies its way to a "World's Largest" title


Qualifiers are a lot of fun. Example: Greenland is the world's largest island. The world's largest lake is the Caspian Sea.

But the world's largest island on a lake, on an island, on a lake, on an island?

Then the title goes to Volcan Point in the Philippines. Treehugger has a great series of zoom-in photos that show you how that complicated geological title was won.
