Small Impacts at Slope Streak Apexes

This image shows some dark slope streaks where small impact craters are visible at their apexes. These craters have little splashes of dark ejecta, which indicate that they were throwing up the same dark-toned material that the slope streak has revealed.

These dark slope streaks and the medium-toned one to the left show longitudinal ridges that are indicators of the flow of material during the slope streak event. Older, almost completely faded slope streaks can be seen to source off of the crater in the upper right corner of this portion of the image.Written by: Ross A. Beyer   (30 October 2007)
