The layers of red sandstone and mudstone found here were formed in desert conditions; some of the sands show cross-bedding formed by wind-blown dunes, whilst mudstone layers occasionally show cracks that formed as the mud dried out after occasional rainstorms. More evidence for a desert environment comes from the recent discovery of scorpion prints at this site.
