It is often cut into flat slabs to best show the layering, and nicer pieces are even framed for display.\u003c\/p\u003e\n\u003cp\u003eThe orange-red coloration of these arches is caused by iron.

The dark iron bands are harder than the surrounding sandstone and create ridges as the softer material is more quickly sandblasted away—just like the material would erode in nature.
