Interim Geologic Map of the North Ogden Quadrangle, Weber and Box Elder Counties, Utah

The North Ogden 7.5' quadrangle is in the eastern Basin and Range Province in the northern Wasatch Range, Utah. The Wasatch Range forms a high ridge between Ogden Valley to the east and the Great Salt Lake Valley to the west. Ben Lomond and Willard Peak (just north of the quadrangle) form the prominent ridge north of North Ogden Canyon. South of North Ogden Canyon, Lewis Peak is the highest point on the ridge that continues south to Ogden Canyon. Ogden Canyon bisects the southeast corner of the quadrangle. In the northeast part of the quadrangle, the North Fork of the Ogden River flows south toward Pineview Reservoir in the adjoining Huntsville quadrangle. Several smaller ephemeral and perennial streams are present in the quadrangle. Most of the Wasatch Range within the quadrangle is within the Uinta-Wasatch-Cache National Forest. The west part of the quadrangle includes parts of the cities of North Ogden, Ogden, Harrisville, Pleasant View, and the Business Depot Ogden, an industrial park situated in northwest Ogden. The east part of the quadrangle in Ogden Valley includes part of the community of Liberty. This new map provides geologic data for a variety of derivative uses. The Utah Geological Survey (UGS) Geologic Hazards Mapping Initiative (Christenson and Ashland, 2007; Castleton and McKean, 2012) will use this mapping to identify and delineate potential geologic hazards for UGS geologic hazard maps of the quadrangle.
