Indecipherable North Polar Landscape (Original NASA/MGS/MSSS b/w Frame)

Original caption:"This MGS-MOC image shows a slope on which layered materials are exposed by erosion in the North Polar Region of Mars. Wind streaks are also evident in this Summertime scene.
The layers that make up the material beneath the ice of the North Polar Residual Cap are typically considered to be a mixture of some amount of dust and ice, but the proportions of these constituents are not known".
