This digital dataset represents geologic features of the Interim Geologic Map of the Provo 30' x 60' Quadrangle, Utah, Wasatch, and Salt Lake Counties, Utah. The Provo 30' x 60' quadrangle covers the populous Wasatch Front in Utah Valley and the adjacent Wasatch Range. In the quadrangle, Precambrian to Cretaceous sedimentary strata are deformed by Late Cretaceous to early Tertiary contractional folding and faulting of the Charleston-Nebo thrust system of the Sevier orogeny, middle Tertiary regional extensional collapse or relaxation that was accompanied by igneous activity, and late Tertiary to recent basin-and-range extensional faulting. Much of the east part of the quadrangle is covered by Tertiary strata that were deposited between the Sevier orogeny and the middle Tertiary extension. The most prominent feature of the basin-and-range extensional faulting in the map area is the Provo segment of the Wasatch fault zone, which separates Utah Valley from the Wasatch Range. Utah Valley is covered with late Quaternary surficial deposits that are mostly due to late Pleistocene Lake Bonneville. Upper Pleistocene glacial deposits are present at higher elevations in the Wasatch Range.
