This is the rock "Chimp" photographed by the Sojourner's front cameras on September 15, 1997. Fine-scale texture on Chimp and other rocks is clearly visible. Wind tails, oriented from lower right to upper left, are seen next to small pebbles in the foreground. These were most likely produced by wind action. Courtesy of NASA.
