JPL Captures Image Of Avalanche On Mars

And no, not evidence of an avalanche, or the aftermath of an avalanche, but an avalanche that was happening as the Mars Reconnaissance Orbiter passed over it on February 19th. The image shows dust and ice sliding down a 2,000-foot high cliff. Pretty darn cool. When a JPL probe captures a current event in our solar system, it is usually an active volcano (Io), or a giant storm (Saturn, Jupiter). But this image is a dramatic surprise, instantly recognizable as a quick event.
