Note 47 — Chapter XVIII · VOYAGE FROM MUSCLESHELL RIVER TO FORT MC KENZIE, FROM JULY 28TH TO AUGUST 9TH
Hannibal Evans Lloyd translation
Dauphin's Rapids became a prominent landmark on the upper river. They were located about six miles below Judith River, and formed a troublesome obstruction. According to Culbertson's reminiscences, they were named for Antoine Dauphin, who was here detected in a liaison with a Blackfoot woman. He was one of the first victims of smallpox in 1837.—Ed.
