Articulated Building Blocks — HAPPY FATHER’S DAY

“List of places with columnar jointed volcanics” is a Wikipedia page, over a hundred sites across the globe and high resolution images of Mars, these columns of Giant’s Causeway are no less marvelous for being the most famous of a phenomenon well documented.

A pile of articulated blocks, ready for assembly, next to orderly placed columns forming a pavement into the sea. Across the way, on the Isle of Mull, Scotland, a matching pavement. “Jointed” means one surface of each block is convex, the other concave, two blocks fit together.
