Only subtle albedo changes have occurred in this complex mixed-tone streak since the Mariner 9 coverage. This complex streak seems to be the result of deflation of low albedo material from the crater at upper right. The numerous bright streaks outside the large mixed-tone streak are interpreted as accumulations of dust storm fallout. Craters and isolated hills seem to produce similar bright streaks. The image is about 240 km across.
