Esker and parent glacier in Phlegra Montes
Planetary Geomorphology Image of the Month, February 29, 2016: Colman Gallagher (University College Dublin). Eskers are sinuous ridges composed of deposits (Image 1) laid down from meltwater flowing in tunnel-like conduits beneath glaciers (Image 2). On Earth, eskers are common components … Continue reading
Southern polar eskers point to warmer past
Ice caps and glaciers on Mars today are “cold based,” meaning they are frozen solid to the ground beneath them. Scientists think the ice has been this way for most of the Amazonian period, the latest chapter in Mars’ geological … Continue reading
