In geology, an unconformity is a buried erosion surface, where the bedding layers don’t match. It doesn’t mean a mismatch in attitudes and beliefs, with rebellious behavior like streaking. But Mars does have streaking of a different kind, from the wind.

This oblique image of part of the North Polar layered deposits, acquired in the summertime, shows both phenomena in the upper and lower panels, plus a topographic bend in the middle panel. Blue areas in this enhanced color image are covered by frost, whereas the darker colors are from differences in contamination and texture of the icy layers.
