The agricultural area of the Uinta Indian Reservation is within the Uinta Basin. Its center is about 105 miles east of Heber and 90 miles northeast of Price; the two nearest railroad stations. The Reservation contains in all some 2,650,000 acres; but from this must be deducted, by allotments to the Indians and for mountainous land, about 2,000,000 acres, leaving approximately 650,000 acres for agriculture. The best and greatest amount of this is to be found in the area bounded on the south by the Duchesne River, on the west by the Duchesne River and Rock Creek, on the north by the high Uinta Mountains, and on the east by the boundary of the Reservation. This is an area 25 by 40 miles, containing within its boundaries Fort Duchesne and the Whiterocks Indian Agency.
