Mount Timpanogos, Wasatch Range, Utah County, Utah
Photographer: Jason Berry
Thousands of years of precipitation, wind, and glacial erosion have sculpted the east face of the Mount Timpanogos massif. The steep cliffs and snow-covered ledges of the Oquirrh Formation exposed on Roberts Horn (10,953 feet) are reminiscent of the Canadian Rockies.

Framed by blooming gray rabbitbrush (Chrysothamnus nauseosus) above the east shore of Deer Creek Reservoir, Mt. Timpanogos is formed of Pennsylvanian-age, shallow- marine limestone and sandstone of the Oquirrh Formation. The small patch of snow is in Cascade Cirque, one of several glacier-carved basins on the east side of the 11,749-foot-tall mountain.
GEOLOGIC MAP OF THE PELICAN POINT QUADRANGLE, UTAH COUNTY, UTAH
Barry J. Solomon, Robert F. Biek, and Scott M. Ritter
This quadrangle is located in central Utah within the eastern Basin and Range Province. The quadrangle includes the northern part of Utah Lake in western Utah Valley, the northern and northeastern lakeshore, and Pelican Point, extending into Utah Lake from the eastern edge of the Lake Mountains. Bedrock near Pelican Point includes Mississippian-age sedimentary strata on the eastern limb of the Lake Mountains syncline. The majority of the quadrangle is covered by Utah Lake, which is underlain by normal faults that form the western boundary of Utah Valley. Surficial deposits along the lakeshore are primarily associated with lacustrine deposition from Holocene Utah Lake and its precursor, late Pleistocene Lake Bonneville.

SURFICIAL GEOLOGIC MAP OF THE SALT LAKE CITY SEGMENT AND PART OF ADJACENT SEGMENTS OF THE WASATCH FAULT ZONE, DAVIS, SALT LAKE, AND UTAH COUNTIES
(digitized from U.S. Geological Survey Miscellaneous Investigation Series map I-2106, 1992)
Stephen F. Personius and William E. Scott
This map shows the surficial deposits and the faults that offset them along the Salt Lake City segment and adjacent parts of the Weber and Provo segments of the Wasatch fault zone in north-central Utah. The map area includes the central and eastern parts of the Salt Lake Valley, including metropolitan Salt Lake City and its southern suburbs. Although a major surface-faulting earthquake has not occurred on the Wasatch fault zone since the state was settled in 1847, the geologic record contains abundant evidence of large earthquakes during Holocene and late Pleistocene time. The size, age, and distribution of fault scarps produced by these prehistoric earthquakes can be used to determine the most likely sites for future earthquakes, and are therefore the principal focus of the map.

The Utah Geological Survey’s newest geologic maps could prove useful in efforts to address geologic hazard and resource issues in Utah County. The maps cover parts of central and southern Utah Valley and surrounding areas.
The maps, each of which covers an area of about 55 square miles, include the Goshen Valley North (Map 230), Lincoln Point (Map 232), Provo (Map 233), Soldiers Pass (Map 235), and West Mountain (Map 234) 7.5’ quadrangles. Collectively, the maps include West Mountain, the southern part of the Lake Mountains, and parts of Goshen and Utah Valleys, as well as parts of the communities of Provo, Springville, Spanish Fork, and Payson.

GEOLOGIC MAP OF THE PROVO 7.5′ QUADRANGLE, UTAH COUNTY, UTAH
Barry J. Solomon and Michael N. Machette
The Provo 7.5′ quadrangle covers east-central Utah Valley and includes Provo, the third largest city in Utah. Hobble Creek, the Provo River, and Spanish Fork are the primary streams in the quadrangle, flowing westward from the Wasatch Range to the Provo Bay portion of Utah Lake. U.S. Interstate Highway 15 extends from north to south through the map area. Included are two plates—a geologic map at 1:24,000 scale and an explanation sheet.

GEOLOGIC MAP OF THE GOSHEN VALLEY NORTH QUADRANGLE, UTAH COUNTY, UTAH
Donald L. Clark, Robert F. Biek, and Eric H. Christiansen
This quadrangle is located in central Utah within the eastern Basin and Range Province, and includes parts of Goshen Valley and the Mosida Hills (also called southern Lake Mountains) along the west and south margins of Utah Lake. Bedrock in the northwest part of the map area includes folded and faulted Mississippian-age strata and a few exposures of Tertiary volcanic rocks related to the Soldiers Pass volcanic field. The majority of the quadrangle is covered by Quaternary surficial deposits, which are primarily associated with lacustrine deposition at and near the Provo level of Lake Bonneville, and with subsequent alluvial-fan development.
