Martian Plumes Stump Scientists

Massive, towering plumes stretching into the martian sky. Sounds like something out of a sci-fi novel, right? Well, they could be, because scientists are pretty stumped.
The plumes, which reportedly reach more than 150 miles above the surface of Mars and spread between 300 and 700 miles wide, have appeared at least twice on the red planet.
The first time was in March of 2012 when a plume appeared and stuck around 11 days. In April another plume appeared and lasted 10 days.
