Opportunity Pancam: Opportunity's Pancam cameras captured this image of tendrils
while exploring the bottom of Endurance Crater.  Resources were tight, so this
shot was allocated only half a frame (1024 x 512 pixels). The dune field was
inaccessible except for remote sensing, as there was concern that the rover would
become trapped. The dunes and tendrils, also visible in orbital images, remain
untouched by the rover. <
