Nevada's Elko County was not, initially, a prominent mining region, but completion of the transcontinental railroad in 1869 permitted the extensive development of its vast rangelands by cattlemen. There is little evidence of activity there by Utah groups in the nineteenth century, but both the northern Wasatch Front and the Elko country were in the path of several large-scale western movements of cattle, and there were cordial contacts between Nevada and Utah livestock interests. 2^ 25Arrington, "The Richest Hole, " pp. 57-65. 26Edna Patterson, Louise Ulph, and Victor Goodwin, Nevada's Northeast Frontier (Sparks, Nev.: Western Printing and Publishing Co., 1969), p p . 207-210.
