Having returned overland, Kienzle made a report on the supply situation. A porter could carry a load equivalent to 13 days' rations. If he carried rations for a soldier, between them, they would consume the load in 6½ days. This made no allowance for ammunition, other necessary equipment or the porter's return. The trek to Kokoda was 8 days. He concluded that operations could not be sustained without large scale air drops occurring. Aerial resupply commenced with drop sites at Kagi and Efogi but neither site was particularly suitable. Significant quantities fell outside the drop zone and could not be recovered. Unreliable maps or poor visibility in the drop zone meant that supplies were often misdropped. Recognising that a better drop zone was needed, Kienzle set out on 1 August, to find a large open area he recalled having seen from the air. On 3 August, he identified the smaller of two dry lake beds near the crest of the range, which he called Myola. Kienzle immediately requested that dropping begin at Myola. Access to this large area alleviated the proportion of supplies lost to the jungle. It also made the task of carriers achievable. He set about establishing it as a supply camp and cut a new track towards Eora Creek. It joined the existing track at Templeton's Crossing, which he also named.
