Figure 13. (a) Oblique aerial photograph of offset grabens (1, 2, 3) in Canyonlands National Park, Utah. At the terminations of individual grabens, the main faults branch into a series of splays that form relay ramps between overlapping, like-dipping faults and complex, conjugate arrays between oppositely dipping faults. (b) Sketch map of the graben systems in Canyonlands National Park, Utah, showing a series of offset graben systems formed by orthogonal extension and linked by complex accommodation zones of interlocking faults.
