Gordon Osinski, a professor of earth sciences at Western University, said: “Devon Island is one of the best analogues we have for Mars here on Earth – it is a cold, dry, polar desert, and the glaciation is largely cold-based.”
In total, the researchers analysed more than 10,000 Martian valleys to better understand how they were created.
According to study co-author Mark Jellinek, the results have produced the very first evidence of Mars’ valleys being shaped by subglacial meltwater erosion.
He said: “The findings demonstrate that only a fraction of valley networks match patterns typical of surface water erosion, which is in marked contrast to the conventional view.
