The Smithfield quadrangle is located on the east side of Cache Valley and the west side of the Bear River Range. Approximately 2,100 feet of Late Precambrian rocks and about 11,500 feet of Paleozoic strata are exposed in the mountains while Tertiary and Quaternary deposits, which oil-well logs indicate as several thousand feet thick in the valley, are exposed along the valley margin. The Tertiary Salt Lake Formation rests unconformably on Precambrian quartzite and Paleozoic units, and Lake Bonneville deposits overlap Cambrian rocks and the Salt Lake Formation.
