Dark slope streak
Dark slope streaks are narrow, avalanche -like features common on dust-covered slopes in the equatorial regions of Mars . [2] They form in relatively steep terrain , such as along escarpments and crater walls. [3] Although first recognized in Viking Orbiter images from the late 1970s, [4] [5] dark slope streaks were not studied in detail until higher-resolution images from the Mars Global Surveyor (MGS) and Mars Reconnaissance Orbiter (MRO) spacecraft became available in the late 1990s and 2000s.

Many places on Mars show dark streaks on steep slopes , such as crater walls. Dark Slope Streaks have been studied since the Mariner and Viking missions. [1] It seems that the youngest streaks are dark and they become lighter with age. Often they begin as a small narrow spot then widen and extend downhill for hundreds of meters. Streaks do not seem to be associated with any particular layer of material because they do not always start at a common level along a slope. Although many of the streaks appear very dark, they are not as dark as they seem; the darkest streaks are only about 10% darker then the sourounding surface. Observations with the Mars Global Surveyor have found that new streaks have formed in less than one year on Mars. |
