Dynosaur Rock Hvítserkur, Vatnsnes, Iceland

Dynosaur Rock Hvítserkur is a 50 ft-high (15 m-high) sea stack just off shore on the eastern side of Vatnsnes, Iceland. Hvítserkur, which translates to "white shirt" and derives its name from being covered in shag and cormorant guano, is nearly 50 feet from the sea.
Once the plug of a volcano, over the years the craters surrounding the rock plug gave way to the pounding Atlantic Ocean leaving only the unusual outcropping Hvítserkur behind. Curiously Hvítserkur itself would have given way to the ocean as well, had its foundations not been shored up with concrete some years ago. Said to look like a dragon drinking from the water, the Icelandic legend has it that it was a troll who forgot to retreat from the light and was turned to stone in the sunrise. The geological oddity was commemorated on an Icelandic stamp in 1990.
