This part of Hadley Rille is far south of the landing site. Lines of outcrops of mare basalt in the upper rille walls suggest thick layering in the basalt. Notice how the edges of the rille stay parallel to each other. One origin suggested for the rille is that it is a graben or fault valley. In its present form, however, the rille could not have formed as a fracture because the sides will not fit back together.   -K.A.H.
