Note 36 — OREGON EXPEDITION

Sweetwater River, a western affluent of the North Platte, rises in the Wind River Mountains, and for over a hundred miles flows almost directly east. The name is supposed to be derived from the loss at an early day of a pack-mule laden with sugar. Wyeth speaks of "crossing over" to this stream, because the trail abandoned the North Platte, which here flows through a formidable cañon, and reached the Sweetwater some miles above its mouth.—Ed.
