Soil salt concentrations as indicators of prior lake levels: Lakes Bonney and Vanda

In the belief that geochemical techniques may assist to unravel the complexities of the Antarctic glacial moraine, a project was undertaken to investigate the concentrations of salts in the soils on the valley sides above Lake Bonney and Vanda. Obviously higher lake levels would leach out the concentration of salts in the soils whereas areas not inundated by ancestral lake levels should have much higher salt concentrations.
