The cavalry is continuing its pursuit, and Sergeant Tibbs periodically sends messengers back to his base to keep it informed of his whereabouts. Eventually, the patrol is whittled down to just Tibbs and two others. Tibbs kills them and persuades Colorado he should be allowed to join the gang. After another shoot-out with the Apaches, and crossing dangerous river rapids, they reach "Shaking Rock", the location where according to the map the gold is. MacKenna tells Colorado they will see the canyon the next morning.
