The pattern shown in the above image is believed to be caused by the pressure of gas trapped underneath a thin ice surface. The ice surface thins due to seasonal temperature changes which enables underneath gas to find small cracks on surface and leak out. The gas, which could have been trapped for years, often carries small dusts from underneath the ice. (HiRISE deputy principal investigator Candice J. Hansen-Koharcheck)
