Geomorphological and glaciological features are represented on a georeferenced satellite image mosaic of the Mt. Murchison quadrangle (73°-74° S, 162°-166°30' E) at the scale of 1:250,000. Landforms and deposits of glacial and periglacial environments, forms related to mass wasting, wind action, weathering, and geological structures are identified and mapped. The chronological sequence of landforms and deposits, morphography and lithology are also indicated. Glacier velocities (up to 180 m a-1) and ice front fluctuations (1964-1999) have been determined by analysis of aerial photography and satellite imagery. Airborne radar surveys reveal that the greatest ice thickness (ca 1500 m) is located at the grounding zone of Aviator Glacier. Up to 1000 metres of ice bury the subglacial relief of Deception Plateau, Hercules Névé and the Deep Freeze Range.
