The western bounding fault of the Cremation Graben truncated by the Great Unconformity. Cambrian Tapeats Sandstone (horizontal) overlies Precambrian Vishnu schist on far wall (center right), and sedimentary rocks of the Grand Canyon Supergroup on the near wall (at left, dipping left). The fault dips steeply down the gully between them.
