New Zealand’s Moeraki Boulders


Here’s something strange.   On a small stretch of Koekohe Beach — about halfway up the Pacific Coast of New Zealand’s South Island — there’s a group of a few dozen spherical rocks.  The biggest are about six feet in diameter.  Stranger still:  a few are broken open, revealing that the inside is hollow, and lined with crystals.  It’s Land of the Lost meets Mork from Ork.

The Moeraki Boulders are a New Zealand landmark.  They’re similar to the softball-sized geodes that are common in North America,  except they’re so big you can crawl inside the hollow middle of a broken one.  There are lots of legends about where they come from, but the most plausible one is pretty boring (something about geological “concretion” of calcite sediment) and doesn’t involve aliens or sleestaks (or even crop circles).
