| Summary: | Tentative characterizations of several Mariner 6 and 7 Martian surface features, made by the senior author in the absence of previous knowledge about Mars, are presented. The ridges in 7N17 are interpreted as a glacial moraine; barchane or parabolic sand dunes are identified in 6N5; and thermokarst collapse features, possibly produced in permafrost by Martian geothermal activity, are proposed in 6N8 and 6N14, in agreement with the suggestion of Sharp et al. (1971). |
