File:Silver Spur Apollo 15 telephoto.jpg

Apollo 15 Commander Dave Scott took this 500-mm telephoto lens picture of Silver Spur during the SEVA at about 106:58:07 Ground Elapsed Time. Silver Spur is named for Caltech geologist Lee Silver. Note that there appear to be two systems of lineations in Silver Spur. One set consists of what appear to be about ten thick beds which appear to dip down from right to left as seen from the LM. As discussed in the Apollo 15 Preliminary Science Report, this set of lineations may well represent real structure in the mountain. The second set of lineations consists of closely-spaced, nearly horizontal lines. These may be lighting artifacts. Scan by Kipp Teague.
