SUMMARY:Climate Change on Mars: Could extreme axial tilt drive glaciers to
  low latitudes? - Andrew Britton

DESCRIPTION:Glaciation is a dominant geological process on Mars and is res
 ponsible for shaping considerable amounts of its landscape. Today\, martia
 n glaciers reside only in polar regions\, however there is evidence that p
 ast glaciation may have extended as far as the Martian tropics. Extreme ch
 anges in obliquity\, when the axis of Mars was tilted as much as 45º\, ma
 y have caused extreme changes in the Martian climate\, allowing water ice 
 to remain stable at surprisingly low latitudes. In my research\, I examine
  glacial features in Mamers Vallis\, a NE-SW trending valley located at 36
 .5º N latitude. Using satellite imagery\, GIS\, crater statistics\, and a
  3D digitial terrain model program\, I can determine the minimum age of th
 e glaciation and compare it with the date of the most recent extreme axial
  tilt. \n
