This part of the ridge (Fig. 76) appears to have flowed over the ground to the right. A careful search will reveal several craters overridden by the ridge along its right edge. A large oblong crater on the ridge near the bottom of the photograph has evidently been distorted by the ridge; in fact, the right edge of the crater seems to be cut off. (See arrow.) One can imagine that a sheet of soft putty might form a similar ridge if it were thrust over to the right. Model experiments and observations of deformed rocks on Earth have shown that large masses of rocks, even hard rocks like basalt, can behave like putty over sufficiently long intervals of time.   -K.A.H.
