Geologic Map of the Hurricane Quadrangle, Washington County, Utah (GIS Reproduction of UGS M-187 [2003])(M-293DR)

By: Robert F. Biek

In 2021, through U.S. Geological Survey cooperative agreement G20AC00389 (2020) funding, the UGS compiled geologic map 187 (2003), into a new GIS database and Geologic Map Schema (GeMS). During this project, the UGS made minor changes to the geologic map based on recent geologic studies in the area. See Errata Sheet at the back of the text booklet for a detailed list of changes.

The Hurricane quadrangle lies in the transition zone between the Colorado Plateau and Basin and Range physiographic provinces. About 8,200 feet of sedimentary rock ranging in age from the Early Permian Queantoweap Sandstone to the Late Cretaceous Iron Springs Formation is exposed in the quadrangle. Eight Quaternary basaltic flows or groups of flows, five cinder cone complexes, and a variety of Quaternary deposits are also present. The strata have been affected by both the Late Cretaceous Sevier orogeny and late Cenozoic extension.
