Wind Carved Rock on Mars

November 09, 2016 ・0 comments


The distinctively fluted surface and elongated hills in this image in Medusae Fossae are caused by wind erosion of a soft fine-grained rock. Called yardangs, these features are aligned with the prevailing wind direction. This wind direction would have dominated for a very long time to carve these large-scale features into the exposed rock. via NASA http://www.nasa.gov/image-feature/wind-carved-rock-on-mars powerd by primes
