Dante's Inferno

Forced to find new river crossing points, the wildebeest descend into individual despair and collective chaos. Fast currents and steep banks all but deny escape onto the tree-covered far side. New arrivals try unsuccessfully to scramble over the lead group that cannot climb quickly enough onto the available dry ground. Within minutes, the riverbank is lined with drowned wildebeest that will eventually be marooned on rocks well downstream where the vultures and crocodiles were waiting.
