This report presents the observations collected by B. Walpole and A.A. Opik during a five days journey in June, 1952. They were accompanied by A.D.M. Bell, resident geologist, Alice Springs. In addition a substantial amount of information on the geology of the area, collected by B. Walpole on his previous visit and communicated to the present writer, has been used in this report. The sequence of the rocks as represented here was originally outlined by B. Walpole. From the amount of information now available, it will be possible to produce a more detailed map on the basis of air photographs, which B. Walpole intends to do. The upper Proterozoic age of these sediments and the presence of Collenia was first recognized in the Mt. Marumba by Haddon F. King on a recent visit. On H.T. Jensen's map (1915) the banks of the Wilton River are coloured as "Cambrian limestones and quartzite". On the map of the Commonwealth of Australia by E. David the same rocks are referred to upper Proterozoic and in the text (1950) as undifferentiated Cambrian and upper Proterozoic.
