A kilometer into the jungle, the banks rise up into vertical walls of stone that climb higher and higher above the water’s level until they actually overhang the river. There is a hollow in the stony channel where the river broadens out; just upstream is the waterfall. At this point the road makes a left turn directly into the rock wall, and stops. Everyone gets out of the Mercedes: Goto Dengo, The General, his aide, and Captain Noda. The river runs over their feet, ankle-deep.
