Nature / Sandstone Passage Of Petra

I took this picture when walking in between sandstone passage or the "Siq" to the "Treasury" at Petra. This sandstone layer was created due to geological process that take millions of years. When I took this picture, the outside temp was 40 celcius, but in the shade it was like less than 30 celcius. The sun light when shine upon the sandstone sediments created some sort like a golden color.
