Well - I am back from Libya - in case you hadn't guessed!

This rock arch is close to the UNESCO site where the rock art and engravings showing the wildlife of the area 12.000 years ago are found. The subjects include; elephant, giraffe, rhino, crocodile, ostrich etc - species associated with savanna. This demonstrates how young the Sahara is - the drying out began at the end of the last Ice-Age.

This arch is given as 150metres high - it is massive. Although it is mentioned in all the guide books it does not seem to have a name. We camped on the far side of the arch in the Wadi. The Acacus contain a huge number of rock arches - maybe as many as Arches National Park in Utah. This is much drier however, far less vegetation and as the picture shows - lots of drifting sand.

The site is located in the far south west - close to the borders with Algeria and Niger.

I cropped the forground to get rid of the tyre tracks - although remote - 2 days journey from the tarmac - the tyre tracks last for ages in the desert floor.

Hi James.
Great composition. The rocks create really wonderful shapes and textures. Nice colour and light. Well done.
Regards, Steve.

Hi James,
Welcome back! Very nice combination of light and shadows. I like the composition. Wouldn't think the arch was that huge without the foreground.
Best wishes,
Hakan

Hello James,
This is a very interesting and unusual picture to me. I like the texture that you captured on the sand, those nice colors, details and DOF. Exposure is interesting too. I wonder what color the sky was as it seems that the rocks in BG are a little OE and I guess that you didnít have the choice to do it this way to expose the foreground correctly. It must have been difficult to calibrate this picture with those zones of shadow. Well done!

A magnificent edifice carved out by nature over centuries and millennia, James.
It is good to see a very fresh picture from your camera. I am sure you must have had whale of a time in this remote corner of Libya known for the rock arches.
Despite the fact that you had to draw back considerably to get the entire structure within the frame, its mammoth size is unmistakable.
Very well captured image. Very good contrasts, and I like the way you have framed the ridge across the Wadi through the arch itself.
Well done and welcome back.

What an interesting formation James. I love all the shapes and curves in your image. The wide range of values would have been difficult to expose for. This scene would have been a good one take at several different exposures and combined in Photoshop.

Hi James,
Goregous capture of this great formation with sharp details and beautiful colors. I think it looks a bit like an inch worm profile.

Cool rock formation. I find that interesting that it is not that old of a desert. This is a great travel photo James. Did you get any pictures of the animal engravings? :)

Being a novice in the world of photography I won't even attempt to critique this photo. It is stunningly beautiful ! What more can I say? Your notes are interesting and informative. TFS Mish

PS The way it rises, undulating, from the sand makes me think of the creatures in the novel Dune... that lived under the deserts... were they called Sand Worms?

Beautiful pic with lovely tones.

Your notes are very interesting, describing further than the subject itself.

I looked up when the agriculture began (-6000). So the dry-out of sahara began before we start messing up the planet. At least we don't get the blame for that one. (although we are known to be responsible for the increasing rate of sahara extension at the time being)
