An Investigation of Alcoves and Other Unclassified Landforms in the Northern Mid-Latitudes of Mars as Potential Evidence of Past Glaciation [#4041] We map alcoves and potentially icy unclassified landforms in the mid-latitudes of Mars to better constrain past glacial extent and conditions. The distribution and characteristics of these landforms are compared with mapped glacier-like forms.
11:15 a.m.	El-Maarry M. R. * Harish Harrington E.	Comparative Analysis of Glacial Landscapes Across Mars [#4045] We analyze and compare various glacial systems across Mars to better understand how glacier-like landforms develop and evolve, and what this may tell us about the martian climate and the stability of ice over time.
