    On Earth, geologists are pretty familiar with the concept of an esker, a snake-like ridge formation left behind by a receding glacier. Across our planet they can be found in areas where glaciers once dominated the landscape. The same is true on Mars, but eskers also require a time when glaciers could melt. Frances Butcher, a PhD student from the Open University, talks with Jake about these special kinds of Martian eskers that indicate a warmer, wetter environment than we once thought.
