A frame released by NASA from the panoramic sequence taken by Cernan near the rim of Shorty Crater.

The western wall of Shorty Crater is at the right of the image; West Family Mountain, rising 1,000 meters above the valley floor, is in the background behind the Lincoln-Lee Scarp, a mare wrinkle ridge crossing the Valley of Taurus-Littrow.

“The clarity brought on by the lack of atmosphere gives the impression that objects are closer than they really are,” observed Schmitt. “This atmospheric clarity made it difficult to estimate distances, so I used the known distance of my shadow and any given sun angle to calibrate my estimates of near field distances and crater diameters.” (Constantine, p. 139).
