THRUST has moved to the west, at first, parallel to the UNDERLYING BLUE SILT; it is later ROTATED upwardly CW to exhibit the 4 fingers curving upwardly. This would be a ROTATION younger than the underlying silt- which is NOT ROTATING! This shows that the LATERAL GRAVITATION is SHALLOW, and that there is exhibited a small-younger ARC.
IRON STAIN is indicative of the Esperance, but this could be any sandstone older than the OVERLYING TILL.
ORTHOGONALITY is demonstrated by this OUTCROP: RECTANGLES gradually give way (later) to the 4 fingered CW-ROTATING feature. REMEMBER that a HORIZONTAL CCW RISING hill is underlain by a CW rotation; this occurs whenever the slope (scarp adjacent to the hill) is greater than 45 degrees from horizontal- similar to 2 gears meshing in harmony:
