SP-424 The Voyage of Mariner 10

 

Fig. A-31 Discovery Scarp, at latitude 52°S and longitude 35°, was photographed at the first, second, and third encounters. A Mercury I picture (a) shows the scarp transecting craters on the right side of the picture. A smaller scarp runs through the floor of a large crater at the top and into surrounding terrain. This picture also shows two long, narrow valleys consisting of many small craters. Mercury II (b) shows the southern section of the scarp from a somewhat different viewing angle. The two transected craters are not included in this image. Mercury III (c) provides high-resolution detail of the northern section of the scarp and again shows the transected craters. The viewing angle is very similar to that of Mercury I. Note that in the larger crater there is a graben-type valley to the right of the scarp, but no such feature in the smaller of the transected craters.
