Note 45 — JOURNAL OF TRAVELS OVER THE ROCKY MOUNTAINS

The Wind River Mountains are noted in our volume xxi, p. 184, note 35. The trail along the Sweetwater is for the most part over a rough, undulating prairie, but at times the hills force the road close to the river valley. At one place, about thirty-six miles above the river's mouth, the route grows rugged and crosses the river three times. This was usually known as the Three Crossings, and is probably the stretch that Palmer calls the Narrows.—Ed.
