A First Look at a Gullied Slope

A First Look at a Gullied Slope

A First Look at a Gullied Slope
HiRISE has been operating since 2006, and lately many of our observations of gullies are repeat images designed to study changes. However, we are also collecting data over gullies never before seen at this resolution, to study their morphology and allow us to look for changes in the future.

This is the first HiRISE look at a cluster of gullies that appear modified or degraded—the gully fans have ripples and ridges that have formed since the last major gully activity, suggesting that they don’t change very often, but we won’t know for sure unless we look!
