Mapmakers puzzled by vanishing island
The strange case of a phantom island off the coast of Australia.
For centuries the little island appeared on maps of the Coral Sea in the South Pacific. At about 45 square miles, Sandy Island appeared to be a small but not inconsequential piece of rock, elongated like Manhattan in New York yet bigger by half. It was situated off of Australia’s northeast coast, not far from Brisbane.
Then, it wasn’t.

Back in 2000, ham radio operators seeking a remote location for a broadcasting competition had sailed to the Chesterfield Islands in the Coral Sea and wanted to learn about this Sandy Island that maps showed was nearby. But when they arrived at the exact coordinates indicated for the island, they found themselves in open water. No terra firma whatsoever. The island simply wasn’t there.
Despite a letter from one of the ham enthusiasts to the cartographers at National Geographic, a dozen years passed before geologists went for a closer look. They were mystified to find that maps of the seafloor showed no underwater mountain at the coordinates for Sandy Island and wondered how the island could exist with no substructure. A research vessel was sent to the location last year and, arriving at the same coordinates, found what the ham operators did. That is, nothing at all.

Sandy Island, which might alternately appear in your atlas as Sable Island, has now officially been “un-discovered.” It didn’t sink or float away or get swamped under as a result of rising oceans caused by global warming.
Sandy was a phantom. British explorers who claimed to have passed nearby in 1772, a French navigator credited with discovering the island in 1792 and another crew of British sailors who saw it in 1876 were apparently all mistaken. For hundreds of years, everyone simply had it wrong.
As noted in a detailed NPR blog about the ghost island, one would think that in the modern age of satellite mapping, GPS locators, spy satellites, military satellites and naval commanders “wanting to know what not to bump into,” someone would have realized by now that 45 square miles of terra firma appearing on maps had gone missing. But no one did.
At a time when there are no new lands left to be discovered and expand our horizons, and when the Internet can put you on virtually any street corner in the world, it’s a great reminder of just how tremendous our planet is. Meantime, mapmakers are sheepishly removing Sandy Island from their next editions.

In September, I'll turn 38. I'm at the age now where, when people ask how old I am, it takes me a minute to remember. I don't know if that's because I've already been 37 different ages and it's hard to keep straight which one I am now, or if it's because I'm in denial, or if it's because I am going senile. Maybe a combination of all of the above. Regardless, my 30s have flown by and soon they will be but a memory. So, in an effort to preserve the memory I have left (or at least keep a record of it), and to celebrate what has been an amazing decade so far, here are 30 things that have happened to me in my 30s (and will probably happen to you too):
