After a 20-meter (66-foot) drive to the southwest on Murray Ridge, Opportunity’s left-side Navcam took an unfiltered shot looking back along the rover’s track. The local time was nearly 4 pm. Note the low outcrop of rock on the ridge (center). In the distance at right lies a thin line of dunes on the floor of Endeavour Crater, while the crater’s eastern rim segments form an irregular horizon, about 22 km (14 mi) away.
