This is a cropped version of image PIA19936 of Pluto's icy plain Sputnik Planum to provide context for two high resolution images of its sublimation pits (combined as PIA20151). The area covered by the left image of PIA20151 is indicated by the yellow rectangle, and that covered by the right image is indicated by the blue rectangle. The original NASA image was rotated, cropped, converted from TIFF to JPEG and marked with the rectangles by the uploader.
