The form of the coastline around Durdle Door is controlled by its geology--both by the contrasting hardnesses of the rocks, and by the local patterns of faults and folds.The arch has formed on a concordant coastline where bands of rock run parallel to the shoreline. The rock strata are almost vertical, and the bands of rock are quite narrow. Originally a band of resistant Portland limestone ran along the shore, the same band that appears one mile along the coast forming the narrow entrance to Lulworth Cove. Behind this is a 120-metre (390 ft) band of weaker, easily eroded rocks, and behind this is a stronger and much thicker band of chalk, which forms the Purbeck Hills. These steeply dipping rocks are part of the geological structure known as the Lulworth crumple, itself part of a broader monocline (a kinked type of geological fold) produced by the building of the Alps during the mid-Cenozoic.

At sunset everyone stops what they are doing and watches the sunset. If they're lucky they'll see the green flash.

A beautiful sunset and an unbelievable "gradient". I took this photo at Torpedo Wharf in San Francisco, California.

Driving in Death Valley is a unforgettable experience with much excitement–many endless roads and never-before-seen scenic spots of all kinds of rocks and geography. This is one of the roads I drove which was long and seemingly endless...

Cool little falls along a small single lane road in the wilderness of Coos County in Oregon, USA. Creek is the South Fork Coquille River. Couple of stacked images for focus.

I got up early and bussed down to the Lake in Burlington, Ontario. I knew I wanted a slow shutter-speed photo but wasn't sure what to shoot. I just took a photo of how I saw that place at that moment.

This is the first landscape photo I've done. It does a great job of bringing me back to that moment, so I thought I'd submit it!

Taken from the Norwegian beach Grotlesanden just like my previous contribution Light Blue Night. This time around, my aim was to keep the post-processing more clean and natural.
