Downramp Fractures
An 8-image composite created with Hugin.
A relay ramp is a structural feature created by the accommodation of stresses between two related, but disconnected faults. Eventually the relay ramp ruptures connecting the bounding faults. This view is looking down one of the relay ramp surfaces (near Delicate Arch in Arches National Park, Utah).
Multiple fracture sets associated with the deformation events that caused the faults can be seen on the surface of the ramp and in 3-dimensions where the ramp has been breached (so that, now a fault surface connects the bounding faults on either side).
