An area of Bryce Canyon National Park, Utah, known as the Wall of Windows consists of limestone cliffs that have been eroded by water, wind, chemical and physical weathering. Limestone is ordinarily white, but the cliffs and spires at Bryce are coloured by impurities, including iron oxide making the stone brown, yellow, or red. Bryce is part of the Grand Staircase, an immense sequence of exposed sedimentary rock layers that stretch two hundred kilometres in the American Southwest and feature some of the most dramatic scenery anywhere in the world. | |
