Abstract
Abstract The Dry Valleys area is characterised by the presence of a number of lakes and ponds, some of them fresh but others containing extremely saline water. In this repon a general description of the nature of these waters is given. From the geochemical point of view, the most interesting problems concerning the saline lakes are those of salt origin, the evolution of the lakes themselves, and the causes of the unusually high temperature of the bottom water of Lake Vanda. For the possible sources of salts, an explanation using a single source has never been successful, and most workers are now inclined to favour multiple sources.
