Look at the beauty of the sandstone and the bird nest with the red curves and interesting textures reaching for the sky.
The sandstone is composed of sedimentary rock made up of sand-sized minerals or grains of rock. The sand becomes sandstone because of the pressure of the rock layers above it.
In the Southwest, the sandstone is red because it also contains iron oxide. The iron oxide will turn a reddish color for the same reason that iron turns reddish brown when it rusts.
Besides the American southwest, red sandstone can also be found in the West of England and Wales, Mongolia, and parts of Central Europe.
