Compilation of 1970s Woodward-Lundgren & Associates Wasatch fault investigation reports and low-sun-angle aerial photography, Wasatch Front and Cache Valley, Utah and Idaho

OFR-632 insert

By: Steve D. Bowman, Adam I. Hiscock, and Corey D. Unger

This nine DVD set contains a descriptive 8-page report and digital files created from the Wasatch fault investigation project performed for the Utah Geologic and Mineralogical Survey (now the Utah Geological Suvey) and U.S. Geological Survey by Woodward-Lundgren & Associates. The project was performed to identify surface fault rupture hazard areas along the Wasatch fault in Cache Valley. This compilation contains digital scans of three separate Wasatch fault reports, 47 fault maps, and 1382 scanned low-sun-angle-arial photographs (frames). The digital files include aerial photograph scans in TIFF format, fault maps in TIFF and Adobe PDF formats, and index maps in Google Earth KMZ, GIS shapefile and Adobe PDF formats. Specialized software (not included) is required to utilized the Google Earth and GIS files, and can be downloaded from the internet.

This compilation will be useful for professionals involved with paleoseismology investigations; land-use planning and management; government agencies; and the general public and others as a historical archive. Low-sun-angle aerial photography was used to highlight certain topographic features, such as fault scarps and traces, for mapping purposes.

Surface Fault Rupture Hazard Map of the Honeyville Quadrangle, Box Elder and Cache Counties, Utah

OFR-638 Insert, Open File Repot, Honeyville Quadrangle

By: Kimm N. Harty and Adam P. Mckean

This 1:24,000-scale surface fault rupture map of the Honeyville quadrangle shows potentially active faults and special-study areas for the Brigham City and Collinston segments of the Wasatch fault zone mapped using primarily 0.5-meter digital LiDAR data acquired in 2013 and 2014. Fault traces were also mapped using black and white stereographic and oblique aerial photographs and previous published sources for the Wasatch fault zone and parts of the West Cache fault zone contained on the Honeyville quadrangle.

Glad You Asked—Glacial Striations and Slickensides

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.

Stories a Trench Can Tell—Determining St. George Earthquake Threat

Geologists are digging into the Washington fault about three miles south of the Utah-Arizona border in Arizona. “The fault is three miles east of St. George and runs through the nearby city of Washington,” said Bill Lund, UGS senior geologist. “There is evidence of surface rupturing earthquakes. Our goal is to figure out how often the fault has moved and how large the earthquakes have been. That will help us understand the potential for future earthquake activity.”
