THE SOUTH POLAR LAYERED DEPOSITS (SPLD) OF MARS ARE COMPOSED OF PERENNIAL WATER ICE AND DUST THAT SURROUND THE CO2-DOMINATED RESIDUAL ICE CAP (SRIC). THE SPLD MUCH LIKE THE NORTH POLAR LAYERED DEPOSITS (NPLD) ARE THOUGHT TO CONTAIN AN OBLIQUITY-DRIVEN CLIMATE SIGNAL. HOWEVER UNLIKE THE NPLD THE SPLD SURFACE AGE FROM NUMEROUS PREVIOUS CRATER COUNTING STUDIES PLACES THE DEPOSIT AT LEAST ORDERS OF MAGNITUDE OLDER THAN THE NPLD SURFACE AND PERHAPS 10S OF MYRS OLD (FAR EXCEEDING THE MODELED ~5 MYR TOTAL LIFETIME OF THE NPLD). LOW RADAR REFLECTIVITY ZONES (LRZS) UNDER THE SRIC ARE HIGHLY LIKELY TO BE CO2 ICE DEPOSITED IN PREVIOUS ~100 KYR CLIMATE VARIATIONS WHILE THE COMPOSITIONS AND DEPOSITIONAL HISTORY OF LRZS UNDERLYING THE SPLD ARE STILL NOT WELL CONSTRAINED. THE COMPOSITION AND TIMING OF THESE DEPOSITS ARE KEY FOR UNDERSTANDING HOW THE SPLD ACCUMULATED. ADDITIONALLY THE SPLD S POTENTIALLY COMPLEX EROSIONAL HISTORY INDICATED BY ITS HIGH BULK DUST CONTENT COMPARED TO THE NPLD COMPLICATES UNRAVELING WHAT CLIMATE RECORD COULD BE CONTAINED WITHIN THE DEPOSIT. THESE FEATURES MAKE THE SPLD ENIGMATIC BUT CRUCIAL TO UNDERSTANDING THE AMAZONIAN WATER ICE MASS BALANCE OF MARS AND BY EXTENSION MARTIAN CLIMATE HISTORY. A GEOLOGIC MAP OF THE SOUTH POLAR REGION OF MARS WOULD PROVIDE NECESSARY CONTEXT TO SERVE AS THE FOUNDATION FOR THESE INTERPRETATIONS HOWEVER A HIGH-RESOLUTION/LOW-MAP-SCALE GEOLOGIC MAP IS NOT CURRENTLY AVAILABLE. THE PROPOSED WORK WILL PRODUCE A UNITED STATES GEOLOGICAL SURVEY (USGS) SCIENCE INVESTIGATION MAP OF THE SOUTH POLAR REGION OF MARS (70 S TO 90 S) AT A FINAL MAP SCALE OF 1:2 000 000. WE WILL USE THE THEMIS DAYTIME IR MOSAIC (100 M/PIXEL) AS OUR PRIMARY BASEMAP WITH MARS CONTEXT CAMERA (CTX) AND MARS ORBITER LASTER ALTIMETER (MOLA) AS SUPPLEMENTAL DATASETS.
