Notes on 3rd Reconnaissance Flight 24/6/38 This flight was to re-examine the new country discovered yesterday, and to find a route leading direct from the Idenburg to Lake Habbema. This latter purpose was accomplished so far as the section from New Lake to Lake Habbema is concerned. There remains however the section between the Idenburg and the new lake. This, though not of great ele- vation,is difficult country topographically, and carries little popu- lation. Clouds over the mountains forced us to turn back about 9 o'clock without completing the work planned. We have still to determine whether the "Great Valley" drains N.E. to the Idenburg, E. to the same River under the Central Range; or whether, as I think most probable, it cuts through the Central Range to the south coast.
