Geologic mapping and topical studies of the martian polar regions based on Mariner 9 and Viking data have identified major geologic units and structures and their formational sequence. However, several fundamental questions remain poorly answered, such as: (1) What has been the history of ice and dust deposits at the poles and their subsequent modification over geologic time? (2) Is their a signature of melting and discharge from any polar deposits? (3) Can long-term or sporadic climatic and geologic changes of global significance be detected in the polar geologic records? (4) How have volcanism, tectonism, and impacts been involved in the geologic evolution of the polar regions? Here we discuss how these questions are currently being re-examined with Mars Global Surveyor data and new geologic mapping of the polar regions. Additional information is contained in the original extended abstract.
