Seven recipients will be presented with the Governor’s Medal for Science and Technology during an awards ceremony Tuesday at Discovery Gateway in Salt Lake City.

The awards program, started in 1987, recognizes Utah people and companies whose career achievements or distinguished service have benefited the state in the areas of science and technology.

The Utah State Energy Program has awarded a total of $720,000 to several entities to promote energy-related activities.

The grants are from American Recovery and Reinvestment Act funds.

A new report by the Utah Geological Survey shows that Deuel Creek in Centerville Canyon, given the right conditions, could dump 196,000 cubic yards of mud on Centerville homes.

The last time Deuel Creek had a devastating debris flow event was, well, never.

But creeks in similar canyons to the north of Centerville Canyon have produced debris flows, which are characterized by large amounts of mud, rocks, trees and boulders. That’s different from a flood, says UGS geologist Rich Giraud, which is mostly water with some eroded material.

About $8.5 million dollars are now available to local governments. The money represents a portion of the U.S. Department of Energy (DOE) American Recovery and Reinvestment Act -Energy Efficiency and Conservation Block Grant (EECBG), which was allocated in March 2009. The funds were directed to state energy programs, larger cities and counties, and federally recognized tribes.

M-243DMSURFICIAL 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.

Even though we are a “desert” state, Utah’s rivers are world-renowned among river runners and geoscientists. Several of America’s early geologists, including G.K. Gilbert, W.M. Davis, C.E. Dutton, and J.W. Powell contributed to theories of stream evolution from observations made in Utah.

Rivers typically originate in the mountains, flow away from them in a more-or-less constant direction, enter increasingly broad river plains, and terminate at an ocean. But many rivers in Utah flow toward and across mountains, run contrary to valleys, make U-turns, and many never reach the ocean.

slickensidesWhat are those groovy rocks and how did they get that way?
Carole McCalla

On a hike around Lake Blanche below Sundial Peak in Big Cottonwood Canyon, a group of hikers came across long, straight, parallel grooves on a smooth, polished rock surface. Recalling another location where they had seen similar features at the foot of the mountains north of downtown Salt Lake City, they wondered if these markings were formed in the same way. Indeed, what exactly are they and how were they formed?

Although the smooth, grooved surfaces at these two locations are similar, they were actually formed in very different ways.

ss-130PALEOSEISMIC INVESTIGATION OF THE NORTHERN WEBER SEGMENT OF THE WASATCH FAULT ZONE AT THE RICE CREEK TRENCH SITE, NORTH OGDEN, UTAH
Christopher B. DuRoss, Stephen F. Personius, Anthony J. Crone, Greg N. McDonald, David J. Lidke

This report presents new paleoseismic information for the northern Weber segment of the Wasatch fault zone, collected as part of a joint Utah Geological Survey and U.S. Geological Survey fault-trench investigation at Rice Creek. This research, which was partially funded through the National Earthquake Hazards Reduction Program, expands the record of Weber-segment paleoearthquakes into the early Holocene, provides new timing and displacement data for the most recent earthquake, and helps reduce uncertainties in earthquake timing, recurrence, displacement, and vertical slip rate. These results are important for understanding segmentation of the northern Wasatch fault zone and for improving earthquake-hazard evaluations of the region.

ofr-556INTERIM GEOLOGIC MAP OF THE EPHRAIM 7.5-MINUTE QUADRANGLE, SANPETE COUNTY, UTAH
Hellmut H. Doelling, Paul A. Kuehne, and Douglas A. Sprinkel

The Ephraim quadrangle is located about 140 miles south-southeast of Salt Lake City in Sanpete County in central Utah. A diagonal line, extending NE-SW across the quadrangle, divides Sanpete Valley to the northwest, from the Wasatch Plateau. Sanpete Valley is a structural feature in which the San Pitch River flows south along its west margin. Quaternary fans form a gently sloping surface from the plateau front to the floodplain of the river.

Bedrock units are mostly of early Tertiary age. These include the (ascending) North Horn Formation (1100+ feet thick), Flagstaff Limestone (500–1000 feet thick), Colton Formation (1400+ feet thick), Green River Formation (620+ feet exposed), and the Crazy Hollow Formation (less than 50 feet exposed). Of these, the North Horn Formation may also have some Late Cretaceous strata at the base. The older three units are exposed in the Wasatch Plateau, the other two along the plateau-valley margin.
