18 September 1776 The Dominguez–Escalante Expedition came from the east where they crossed Blue Bench and descended into the valley north of the present-day town of Duchesne. "We ascended a not very high mesa Bench which was level and very stony, traveled about three quarters of a league including ascent and descent, crossed another small river River which near here enters the San Cosme (Strawberry River), named it Santa Caterina de Sena, and camped on its banks." "Along these three rivers we have crossed today there is plenty of good land for crops to support three good settlements, with opportunities for irrigation, beautiful cottonwood groves, good pastures, with timber and firewood nearby."
