This terrain looks like lumpy sediment on top of patterned ground. The lumpy sediment is likely just loosely consolidated because it is <a rel="nofollow" class="external text" href="http://static.uahirise.org/images/2016/details/cut/ESP_046562_1005.jpg">covered with spidery channels.</a>
<p>This landform is uniquely Martian, formed in the spring as seasonal dry ice turns directly into gas that erodes channels in the surface.
