Landscape Arch, Arches National Park

This view of Landscape Arch along the Devils Garden Trail was taken in the afternoon. Note the fracture line that is roughly parallel to the underside of the arch. Cracks like this form as part of the process of exfoliation, "the peeling off from bedrock of slabs" of stone "in a series of concentric layers" (Harris and others, 2004, p. 81).
