More Mars Avalanches from HiRISE, Oh My!

By Nancy Atkinson April 7, 2010

Based on this year's observations, these events happen mostly in the middle of spring, roughly equivalent to April to early May on Earth. And, they are indeed more widespread than just this one scarp. All together, it seems this is a regular spring process at Mars' north pole that may be expected every year - avalanche season! This information, in conjunction with the results of numerical modeling of the behavior of the materials involved, will help us find out what is causing these dramatic events.
