This open-file release makes GIS data available to the public during the review and production period necessary for a formal UGS publication. The map may be incomplete, and inconsistencies, errors, and omissions have not been resolved. While the document is in the review process, it may not conform to UGS standards; therefore, it may be premature for an individual or group to take actions based on its contents.The Ogden 30x60-minute quadrangle covers the populous Wasatch Front near Ogden, Utah and the adjacent Wasatch Range and extends eastward into Wyoming north and south of Evanston, Wyoming. In the map area, Precambrian to early Tertiary rocks are deformed by Late Cretaceous to early Tertiary contractional folding and faulting of the Idaho-Wyoming-Utah salient of the Sevier and Laramide orogenies. Tertiary regional extensional (collapse) faulting was accompanied by igneous activity and by late Tertiary to recent basin-and-range extensional faulting. Much of the east part of the quadrangle is covered by early Tertiary and underlying latest Cretaceous synorogenic strata. The most prominent feature of the basin-and-range extensional faulting in the map area is the Weber segment of the Wasatch fault zone, which separates the Wasatch Front from the Wasatch Range. The Ogden, Morgan, East Canyon (Henefer), and Bear River back valleys were formed during extensional (collapse) faulting and basin-and-range extensional faulting. The Wasatch Front and Ogden and Morgan Valleys are covered with late Quaternary surficial deposits that are mostly related to late Pleistocene Lake Bonneville. Pleistocene glacial deposits are present at higher elevations in the Wasatch Range.", "summary": "", "title": "Geologic Layers", "tags": [], "type": "", "typeKeywords": [], "thumbnail": "", "url": "", "minScale": "NaN", "maxScale": "NaN", "spatialReference": "", "accessInformation": "Program Manager: Grant C.
