资源简介：
Three holes were drilled into frozen sediments around Lake Fryxell. The first was 4ft in depth in frozen silts approx 50m NW of the Fryxell Hut. The second hole was 30m east of the first hole and a depth of 16ft. A third hole was drilled approximately 1km east of the second hole to a depth of 46ft. The cores were analysed and the lacustre carbonates within were dated. This was the first time that diamond drilling was used to drill the cores.
