Erosion and what it reveals
About this image
This image is located near the boundary between Syrtis Major and Isidis Planitia. The top of the image shows rough material that has eroded away from the lower portion of the image, revealing an underlying surface that has many small craters. It also reveals an ancient flow lobe that is barely discernible, crossing the southern part of the image (this flow lobe is much easier to see as a smooth region in the context image).
