Summary: 1440
hundreds to thousands of meters of ice can be
deposited in some locations (9).
Recent geological mapping shows fea-
tures at low latitudes best interpreted as gla-
cial in origin (see the figure). Features occur
in isolated low-latitude locations such as the
flanks of theTharsis volcanoes that are rem-
iniscent of moraines, knobs formed as a
residual similar to terrestrial water-ice sub-
limation hills, and flow-line morphology
(10). Remarkably, these are the same loca-
tions for which dynamical models show
preferential deposition of water ice (9).
Thus, the geological evidence supports
the dramatic climate changes that would be
induced by the changing obliquity. Indeed,
large changes in the climate appear to be the
natural consequence of the temporal oscil-
lations of the system.
