Figure 6. Oblique aerial photograph (NASA photo S-78-26931) of western part of Clodine fault, looking southwest toward Figure Four Lake (map 1). R and S identify ridge-and-scale topographic features typical of point-bar deposits. A similar but younger point bar is visible on the inside bend of Figure Four Lake (arrow), a remnant of an old and now-abandoned stream channel. Topographic details of the faulted point bar are best visible on aerial photographs after a heavy rain, when water (light tones) occupies the swales of the point bar and the downthrown side of the fault is flooded. The slope that marks the fault may be followed readily through the fields, but the scarp has been all but destroyed by repeated plowing. Similar relationships have been photographed at other locations along the 12-km length of this fault.
