新的南极海底声纳图像显示，超大规模的冰川线与火星流出通道的纵向凹槽惊人地相似。类似的结果表明，冰在火星上的一些地方穿过沟渠，雕刻出了这些沟槽。火星沟渠中的冰可能像南极的冰流一样，在高孔隙压力下，在饱和水的可变形碎片上移动。在火星上，充满冰的通道底部的水可能来自过去温暖气候或高热流释放的残余水或融化水。
New sonar images of the Antarctic sea floor reveal mega‐scale glacial lineations that are strikingly similar to longitudinal flutes in martian outflow channels. The analogs suggest that ice moved through the martian channels in places and carved the flutes. The ice in martian channels may have moved like Antarctic ice streams on deformable debris saturated with water under high pore pressure. On Mars, water at the base of ice‐filled channels may have come from residual water or melt water liberated during past warmer climates or higher heat flows.
