Based on this photo, what do you think Stađarbjargavík might have to offer?
If you guessed columnar jointing in basalt, you’d be right!
Looking down the fjord, south of Hofsós (in Iceland):
The place is basically a series of miniature Giant’s Causeways, full of unpopulated exemplars of cooling columns!
Little coves separate the small peninsulas, each filled with rounded column bits:
Here’s a spot where one more is about to be added to the sedimentary load:
Visitors can climb all over the place, checking out the expression of the more or less hexagonal columns:
Did you note the glacial striations there? (Of course you did.)
Most columns show “crack panels” of arrest lines along their sides:
On this one you can even make out (via the subtle plumose structure) the joint propagation direction:
It’s a fantastic place. If you ever find yourself in Iceland’s Troll Peninsula, you must visit, and then go for a swim at the incredible Hofsós pool!
