Antarctic geomorphological and glaciological 1:250 000 map series: Mount Murchison quadrangle, northern Victoria Land. Explanatory notes
Geomorphological and glaciological features are represented on a georeferenced satellite image mosaic of the Mount Murchison quadrangle, northern Victoria Land, Antarctica (73-74° S, 162-166°30′ E), at a scale of 1:250 000. Landforms and deposits of glacial and periglacial environments, forms relate...
