Longitudinal section through sediments of the fossil chamber. 1, 2 and 3 indicate positions of the initial excavation, the stratigraphic pit and the third excavation respectively. rocks (up to 15 cm diameter) precludes their downslope transport by the probably maximum water flow rates expected in the cave, although initial emplacement could have been by sediment slump downslope. The cross-sectional shape of the channel varies and appears to be affected by amount of rock in the sediment â wide and shallow where rock is abundant, narrow and deep where rock is absent. Thus depth of erosion on the cone is possibly controlled by the formation of a lag floor, such that continued flows over the cone would leave a lag of bone and rock fragments inhibiting further erosion. Extensive roof collapse has curtailed this process and prevents exploration of the supper part of the cone. The Fan Water flow over the gently sloping fan has cut small channels in the existing sediments close to the base of the cone and the bottom of these channels are filled with a deposit of coarse quartz sand and small bone. Channels in the base of the cone are missing due to erosion by later events, but further downslope the channels grade into tabular layers of clean washed sand interspersed with red sand or clay. This suggests a winnowing process whereby sediments on the cone Aust. Zool. 21(4), 1984 315.
