Figure 1 - Mars ridge

A moderately eroded fluvial sinuous ridge (FSR), with lots of small craters in it, that stands out clearly above the surrounding material.
A moderately eroded fluvial sinuous ridge (FSR), with lots of small craters in it, that stands out clearly above the surrounding material. To the north east it emerges from a small valley and becomes progressively clearer to the west, until it disappears. There is a clear curve in the FSR, likely a meander. North of the FSR is a round, flat feature that was likely an impact crater which was filled with water or sediment. CTX image: MurrayLab_V01_E020_N-20_Mosaic
