7 - Slope Streaks



Amongst these variety of features related to water activity, one of the most prominent are 'slope streaks', stains that run down the slopes of valleys and canyon walls. They are the fastest changing feature on the Martian surface. For every hundred exising slope streaks there are seven more every Martian year.

In September 2005 streaks were found which had not shown up in photographs of the same areas taken in 1999, suggesting that there has been liquid water running on Mars' surface, not even thousands of years ago, but within the previous 6 years.
