Inscription. A perilous ford at Three Island State Park was a formidable Oregon Trail barrier. Those who could not cross here faced a longer, more difficult southern route.

No other ford between Missouri and Oregon troubled them so much. This was their largest river. Using two of three islands, they crossed three channels, but sometimes lost stock and wagons. Many emigrants depended upon Shoshoni Indian guides to get them across safely.
 
Erected by Idaho Historical Society. (Marker Number 198.)
