Having reached the highest point of our route according to plan we discovered something the map had not told us. It was impossible to climb down into the Kingo valley. The river lay deep between mountain sides that were almost vertical. We couldn't find any animal tracks, which usually show the best way across country, and the slopes were covered so thickly with bushes that we could not see the mature of the ground we had somehow to breakthrough to the river which would give us our direction out of the mountain into the inhabit ed lowlands.
