Columnar basalt? I'm lovin' it!

It's never too late to become fascinated with geology and, I'll warn you, such a fascination could very well develop during a visit to the Bay of Fundy! We're surrounded by so much cool geology, you just can't help but find it interesting.

Half the time I have no idea precisely what I'm looking at but that doesn't keep me from being randomly awestruck by Fundy's many rocks & rock formations.

For example, take columnar basalt: these vertical columns are long cylinders with many straight sides (sometime appearing hexagonal from the top). They are the result of the quick cool of lava flow.

There are many basalt cliffs around Bay of Fundy but one of the most accessible and visually intriguing is the famous Balancing Rock on Long Island, near Digby. Here a single column of basalt appears to sit 'balancing' precariously atop the edge of another, while another nearby column pushes up to form a flat step beside its neighbouring columns.

These are two photos I took while hiking there this week.

Terri, we were lucky to visit Grand Canyon last year but I will say that the Fundy shore has its own spectacular geology.
