[Hosea Stout Diary] Wednesday Sep 13th 1848. Moved on passing down a very steep hill in the morning which was rendered dangerous by the late rain.
To day we passed a curious copperas Spring & to night encamped on the top of the dividing ridge between the waters of Green River and Bear river 7700 feet above the level of the sea.
Clear & cold but good grass. Was met several returning to the States to day
