This low Sun angle, high resolution picture shows in greater detail the branching network of lava channels displayed in figure 200. The long shadows along the channel network are formed by its natural levees of chilled lava. The channels branch downslope, as is customary in lava distributary systems on Earth. Small impact craters that postdate the lava flows riddle the channel margins and bottoms and saturate the lava surfaces. Many form lines of secondary craters. Tectonic displacements (faults) offset the lava surfaces and cut across the lava channels; they are, therefore, considered to be younger than the lava channels.   -H.M.
