World-class graben stepover at Devils Lane, Canyonlands National Park, Utah USA

Field view of a world-class stepover (relay-ramp) between two graben-bounding normal faults, Devils Lane graben, Canyonlands National Park, Utah USA, revealing near-tip fault displacement profile and 3D ramp geometry. Vehicle trail for scale. From Schultz, RA, Geologic Fracture Mechanics, Cambridge University Press, 2019. This exposure has been used world-wide by both academic and industry geologists to understand the geometry and evolution of normal-fault systems.
