Athabasca Valles is a young outflow channel system on Mars that may have been carved by catastrophic water floods. However, images acquired by the High-Resolution Imaging Science Experiment camera onboard the Mars Reconnaissance Orbiter spacecraft reveal that Athabasca Valles is now entirely draped by a thin layer of solidified lava—the remnant of a once-swollen river of molten rock. The lava erupted from a fissure, inundated the channels, and drained downstream in geologically recent times… 
Response to Comment on "Athabasca Valles, Mars: A Lava-Draped Channel System"
TLDR
Data from the High-Resolution Imaging Science Experiment camera now confirm that, although certain features exhibit a superficial similarity to ice-related landforms, solidified lava coats the entire channel system of Athabasca Valles, Mars.
Coils and Polygonal Crust in the Athabasca Valles Region, Mars, as Evidence for a Volcanic History
TLDR
High-resolution images from the Mars Reconnaissance Orbiter show that the Athabasca Valles on Mars is volcanic in origin, and 269 spiral coils ranging from 5 to 30 meters wide on the polygonally patterned interplate terrain that are morphologically consistent with terrestrial lava coils that form in zones of flow shear.

TLDR
All the features they described are secondary and postdate the surface by many millions of years, as documented by structural relationships with small, young impact craters.

Evidence from the Mars Express High Resolution Stereo Camera for a frozen sea close to Mars' equator
TLDR
High Resolution Stereo Camera images from the Mars Express spacecraft indicate that evidence is consistent with a frozen body of water, with surface pack-ice, around 5° north latitude and 150° east longitude in southern Elysium, which is a place that might preserve evidence of primitive life, if it has ever developed on Mars.
