Douglas-fir trees by the side of the road, somewhere between Banff and Lake Louise, in Alberta, Canada.
One of the great things about a roadtrip without specific deadlines is that you can stop on the side of the road whenever you want to take some photos, and I did that plenty of times during the few days I had to myself around Banff and Lake Louise.

The Tessellated Pavement is located just north of Eaglehawk Neck, in Tasmania. Nearby, a number of other geological attractions are located, including the Tasman Arch, Devil's Kitchen, and the Blowhole.
However, the Tessellated Pavement was the most intriguing for me, with the rock formation looking very much like it was man-made, due to the very straight and parallel lines in the rock formation.

There are two main types of formations in the Tessellated Pavement, with the pan formations (as shown in the two photos below) being concave (ie, pan-shaped), and the loaf formations (to be shown in a future blog post) being convex like a loaf.
