Olsen, James, Autobiographical sketch 1921, 2.
When we got inot [into] the Platt[e] River valley we found another king of the forrest, the American Buffalo, which roamed those sandy plains of the Platt[e] Valley, they came down from the hills to the river for water by the hundreds and stampeed our cattle, as they were afraid of them.
Well we traveled on and on except Sundays, which was given over to worship and thanksgiving for our deliverance from week to week. So on we went until we reached the noted Echo Canyon of which I will write about later, now through Echo Canyon and down the Weber River to a point below Echo, and then up over what is called the Big Mountain the very top of the Wastach [Wasatch] Range, and then across to the Little Mountain from where we could see the Valley,
