Lake Wilson was examined to see if it contained permanent water. The thickness of the ice was described. 36 holes were drilled and the bathymetry was mapped. Surface sediment samples were collected from most drill holes and the sedimentology described. The temperature throughout the lake was measured and the conductivity was determined down to 70m depth. Samples of water down to 52m were collected and analysed for isotopic content. The chemistry of waters of greater depth could not be determined because of the unexpected depth of the lake.
