One of the remarkable things about the rocks on the Colorado Plateau, such as these visible from Navajo Bridge, is the fact that they are mostly horizontal. Most mountain building forces in the earth seem to bend and tip the rocks, but here they are almost perfectly flat and about 5000 to 6000 feet above sea level. Since most scientists believe these sandstone rocks were made from inland seas or sand dunes, it is interesting that they are so high yet still level.
