Interim Geologic Map of the Salt Lake City North Quadrangle, Salt Lake and Davis Counties, Utah

The Salt Lake City North 7.5′ quadrangle is located in Salt Lake and Davis Counties from downtown Salt Lake City on the east to the Salt Lake International Airport on the west and extends north into Davis County to include the southern parts of the City of Bountiful and City of Woods Cross. The southern boundary of the quadrangle is at approximately 900 South Street in Salt Lake City. The quadrangle contains downtown Salt Lake City, the State Capitol building, the City of North Salt Lake, agricultural land, a number of oil refineries, a part of the Farmington Bay Waterfowl Management Area, and a number of wetlands. The Jordan River flows north through the center of the quadrangle towards Farmington Bay of Great Salt Lake. The eastern part of the quadrangle contains the western part of the Salt Lake salient, which forms an intermediate-elevation, east-west ridge between Salt Lake Valley and the Wasatch Range that separates Davis and Salt Lake Counties. City Creek f lows from the Wasatch Range and empties into the valley in the southeast corner of the quadrangle. The western part of the quadrangle contains Great Salt Lake wetlands and mudflats, and the alluvial plain and deltas of the Jordan River. This project will provide the basis for identifying and delimiting potential geologic hazards in future Utah Geological Survey (UGS) derivative geologic hazard maps, part of the UGS Geologic Hazards Mapping Initiative (Christenson and Ashland, 2007; Castleton and McKean, 2012).
