The Martian terrain as imaged by the Viking Orbiter spacecraft is analyzed for petroglyphs indicating a prior, warmer, wetter climate. Subsurface water is envisioned as causing the channels, through collapse of underground reservoirs, and network channels, from sapping processes. Morphologies resembling frozen and cracked permafrost regions on earth are noted, and the layered terrain near the edge of the north ice cap is taken as evidence of a Martian oscillatory climatic change. A model was presented that the Tharsis volcanoes altered the Martian planetary orientation, caused polar wandering, and left layered terrain near former arctic regions. It is noted that such layered terrain has been observed in abundance. The discussions took place at the Mars colloquium at California Institute of Technology in August, 1981.
