About this work
The sinuous ridges in this image display strong characteristics of ancient meandering riverbeds that are preserved as inverted topography (blue). The ancient river sediments that make up the ridges might have allowed fluids to produce cements (e.g., calcite or iron oxides) to make the channel lithology resistant to weathering and erosion.
