Photo Description

This narrow-angle photograph lies within one of the bright areas of Mars (Deucalionis Regio) and shows in greater detail part of the larger region covered by wide-angle photos 19 and 21. The sharp outlines and apparent freshness of many of the craters on this photograph are particularly striking. However, near the center-left margin are faint outlines of an older and larger crater with suggestions of a double concentric form, which is seen in some craters on the backside of the Moon. On the original photo copy, many well-formed, very small craters not much more than 1,000 feet across are visible. It is a reasonable inference that a still greater number of even smaller craters pock the surface of Mars. The fresh crater, less than 3 miles in diameter, above the center of this picture, lies in the midst of irregular bumpy terrain which may represent sheets of rocky debris thrown out of this and neighboring craters or perhaps some nearby but still larger crater not visible on this photo. Similar bumpy terrain occurs in the upper right corner, and around some of the other craters. Faintly discernible and running roughly northward through the right side of this photo is an irregularly sinuous ridge strongly reminiscent of "crinkle ridges" seen on the lunar surface. The sun angle for this photo is relatively low (late afternoon on Mars), and the dark areas inside some of the sharp fresh craters are almost certainly shadowed. This is strongly suggested by the kidney shape of the darkest area within the largest of the fresh craters toward the top of the photo. If this initial interpretation stands up, then this will be the first definitely recognized shadow cast by topographic features on Mars.
