| Abstract: | Telescopic data on the twentieth-century regressions of Mars' south polar cap have been reexamined for evidence of interannual variability. Several regressions, particularly that of 1956, are found to differ significantly from the mean. The possibility of correlations with major dust storms is explored. |
