Sol 4723, May 7, 2017. Pressure from the advancing season means that Opportunity is not going to drive up and investigate Winnemucca mesa at close range, so mission scientists chose to use the Pancam in high-resolution mode to image it from the head of Perseverance Valley, about 400 meters (1300 feet) away. The result is a near real-color image (Holger Isenberg). Click image to enlarge it.
Winnemucca caught attention when Pancam red-sensitive grayscale images back on Sol 4679 (March 23) showed it to have a bright surface, which is probably caused by accumulations of reddish dust.
