Basalt columns rock!

bal rock sm.jpg basalt bal rock sm.jpgIt'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 in my photos 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.

Hi Terri
I see I'm not the only one with a fascination for the unusual rock formations along the Fundy shore. Your blog sparked a couple of ideas for similar blogs, one of which I posted this week with another to follow. My apologies if I'm trespassing on your territory. Good blog! Keep them coming.
