Mounment Valley-August Sky 60x20byLou Oates Photography.In August you can see many interesting cloud formations in the usually flat blue skies over Monument Valley.Photo was shot around 5:30pm just as the sun sank low enough in the sky to produce the rich red and magenta colors this place is known.The clouds show the turbulent remnants of strong up-drafts from the still-hot sands cooked by the afternoon sun.The tiny black car on the valley floor road gives a sense of scale to this majestic scenery.
