Observations of the initiation and evolution of the 2001 Mars global dust storm
began near Hellas just before southern spring equinox (Ls = 177). Local storms, likely forced by a combination of slope-flow and ice cap thermal contrasts, were observed to propagate along the northwestern rim of Hellas, apparently triggering the global storm.
