Epic Landscapes: Photos from the UK.
Six photos from the winners of the 2010 “Take A View” photography competition from walkmag.co.uk. Photos can be seen in full view here, which include:
- Nicola Harkness: Waterfall of Smoo Burn, seen through the dim light of the second chamber of the cave – a combined sea and freshwater cave in the far north of Sutherland. (main [large] photo)
- Dudley Williams: “Sand Patterns” – photograph of a freshwater run-off across a beach on the Isle of Eigg, Scotland, creating stunning patterns in the sand. The soft tones are provided by the late-winter dawn. (top left [small] photo)
- Stephen Garnett: Image of Malham Moor in winter, North Yorkshire, England. (top middle [small] photo)
- Slawek Staszczuk: View of the South Downs near Kingston, East Sussex, England. (top right [small] photo)

Extreme Geology: The Giant’s Causeway, Ireland and Staffa, Scotland
→ Credit for photos: one, two, and three.These amazing basalt columns cane be found on Staffa, Scotland, and Giant’s Causeway in Nothern Ireland. These geological structures formed from volcanic activity over 50 mya where the slow cooling of basalt creates the hexagonal columns you see today. The process which creates such stunning hexagonal columns is called “columnar jointing”; a process where the basalt rapidly cools from the outside towards the centre, causing it to contract and form these structures.

The White Cliffs of Dover (by Malc H)
The white cliffs of Dover are cliffs which form part of the British coastline facing the Strait of Dover and France. The cliffs are part of the North Downs formation. The cliff face, which reaches up to 350 feet high, owes its striking façade to its composition of chalk (pure white calcium carbonate) accentuated by streaks of black flint. The cliffs spread east and west from the town of Dover in the county of Kent, an ancient and still important English port.
The cliffs have great symbolic value for Britain because they face towards Continental Europe across the narrowest part of the English Channel, where invasions have historically threatened and against which the cliffs form a symbolic guard. Because crossing at Dover was the primary route to the continent before air travel, the white line of cliffs also formed the first (or last) sight of the UK for travellers.
