On a spectacular autumn afternoon, Heber Valley Railroad's 'Provo Canyon Limited' rambles by milepost 16, just north of Vivian Park. Beautifully restored O.S.L. 2-8-0 #618 leads this trainload of lucky passengers along the Provo River. Due to a recent storm system, a light dusting of snow adorns the top of 11,749 ft. Mt. Timpanogos.
