Southern Trough

         This mosaic was acquired by the Mars Exploration Rover Opportunity from Sols 4927 - 4932 (December 3 - 8, 2017). Opportunity's wheel tracks are clearly visible on the far right side of this 148 degree wide mosaic where the rover was looking back uphill at the path she took. The remaining portion of this view is extended along a trough margin to the south of the rover. The southern trough is separated from the northern trough by a mesa-like feature that acts like a "fork in the road" between the two troughs. The full scene of both troughs is visible in the albedo panorama from Sol 4924 where the mesa-like feature is far left frame of the panorama with the northwest trough to the left wrapping around to the other side of the panorama and the southern trough on right of the mesa-like feature. The shadow of Pancam and other parts of the rover in the bottom right of this mosaic look to be stereoscopic in appearance due to the setting sun positioned behind Opportunity during the image capture process changing the shadow length. Pancam's 753 nm, 535 nm, and 432 nm filters were used in making this mosaic. Three versions are provided at full resolution: an approximate true color rendering, a false color rendering which enhances the subtle color differences in the scene, and a stereo anaglyph for 3D viewing through red-blue glasses.
