This image shows a potential outflow channel near Huo Hsing Vallis heading into an old crater. It appears that this crater was filled in, and a higher resolution picture can constrain the timing of potential fluvial activity and lava emplacement. The lava appears to overlay sand and sedimentary deposits. Dunes are also visible in this channel, which could be compared to similar features in Huo Hsing Vallis.
