2018 Lake Bonneville Geologic Conference and Short Course
October 3–6, 2018
Utah Department of Natural Resources Auditorium
1594 West North Temple
Salt Lake City, Utah
Please contact Adam McKean with questions (801-537-3386 or adammckean@utah.gov).
With the publication in 2016 of the “Lake Bonneville: A Scientific Update” book, the Utah Geological Survey is interested in bringing together the geologic community to review and discuss relevant research in the Lake Bonneville basin. The goal of the conference and short course is twofold: (1) to provide a setting for the review and discussion of Lake Bonneville/Great Salt Lake geologic research, and (2) provide education and networking opportunities for the local geologic community.
A registration fee of $26 per day will be charged for all participants (lunch, and morning and afternoon snacks will be provided). The short course will be limited to the first 50 participants. REGISTER HERE

Utah FORGE Project Completes a Two- and Three-Dimensional Seismic Survey
Last week the Utah FORGE project completed a two- and three-dimensional seismic surveys to further characterize the project area’s buried granite reservoir. Specifically, the survey may help to identify any buried faults that might be zones of fluid flow.
Seismic surveys create subsurface images by generating, recording, and analyzing sound waves that travel through the Earth (such waves are also called seismic waves). Density changes between rock or soil layers reflect the waves back to the surface, and how quickly and strongly the waves are reflected back indicates what lies below.
For the Utah FORGE survey, vehicle-mounted vibrator plates (called vibroseis trucks) generated the source waves and a grid of geophones recorded them. The survey included two 2D surveys that were 2.5 miles long and included approximately 160 source points and geophone receivers each, and a 3D survey that covered 7 square miles and included 1,100 source points and 1,700 geophone receivers. The data is now being processed to generate a three-dimensional map of the subsurface reservoir.

2018 Calendar of Utah Geology is the Best Yet!
The Utah Geological Survey (UGS) recently released the 12th edition of its popular Calendar of Utah Geology. The 2018 calendar features inspiring photographs by UGS staff of Utah’s geologic wonders with a brief explanation of how and when they formed.
Weathering and erosion of the Jurassic-age Entrada Sandstone forms a fantastic array of stone structures locally referred to as “goblins.” Goblin Valley State Park, Emery County. Photographed by Gregg Beukelman.
Eight years ago Gregg Beukelman, whose photograph was selected for the calendar’s cover, moved to Utah from Idaho when he landed his current job as a geologist with UGS’s Geologic Hazards Program. After the move Beukelman found himself with free time in what he describes as “hands down the most beautiful state in the nation.”
Beukelman previously had a passing interest in photography, but it was Utah’s incredible landscapes and vistas that stoked his passion. He now spends many of his off-work hours traveling across Utah searching out vistas and awaiting lighting conditions that allow him to create his stunning images. Like other employees whose photographs have been featured in the calendar, Beukelman’s have transformed from nice landscape shots to true works of art.
Beukelman is not alone in his path from geology to photography. The calendar has featured more than 40 UGS geologists. Other staff members have taken an opposite tack and were previously artists who sought employment with UGS because of their love of the outdoors and curiosity about geology. UGS graphic designer John Good and Natural Resources Map & Bookstore clerk Andy Cvar are both featured in this year’s calendar.
Both the artists who have turned to geology and the geologists who have turned to art have contributed to a tradition of growing excellence to create what proves to be the best Calendar of Utah Geology to date!
The 2018 Calendar of Utah Geology is the same price as last year, $4.95 each or $4.25 for orders of 10 or more, and is available at the Natural Resources Map & Bookstore, 1594 West North Temple, Salt Lake City, (801) 537-3320 or 1-888-UTAHMAP. They may also be purchased online.

New Map of Utah Earthquakes and Faults Now Available
Salt Lake City (Sept. 21, 2017) – The Utah Geological Survey (UGS), University of Utah Seismograph Stations (UUSS), and Utah Division of Emergency Management (UDEM) recently published the Utah Earthquakes (1850–2016) and Quaternary Fault Map (UGS Map 277). The new map shows earthquakes within and surrounding Utah from 1850 to 2016, and faults considered to be sources of large earthquakes.
The faults shown on the map are considered geologically active, have been sources of large earthquakes (about magnitude 6.5 and greater) during the Quaternary Period (past 2.6 million years), and are the most likely sources of large earthquakes in the future. Most of the small to moderate-sized earthquakes on the map are “background” earthquakes not readily associated with known faults and too small to have triggered surface faulting (under about magnitude 6.5).
There is a 57% probability (over 1 in 2 chance) that a magnitude 6.0 or greater earthquake will occur in the Wasatch Front region in the next 50 years. To address this threat, the Utah Earthquake Program (https://ussc.utah.gov/pages/help.php?section=Utah+Earthquake+Program) consisting of the UGS, UUSS, and the UDEM, developed the map so the public could more fully understand the hazard from earthquakes and faults, as well as the resulting risk to property, infrastructure, and life safety in Utah. Users of the map will be able to determine past earthquake locations and relative magnitudes (size), along with the locations of active faults and the timing of their most recent movement.
Printed copies of the map are available for $15 at the Utah Department of Natural Resources Map & Bookstore (http://mapstore.utah.gov). The map is also available as a PDF download at https://ugspub.nr.utah.gov/publications/maps/m-277.pdf (44 by 62 inches in size) and can be printed on a wide-format printer.
Additional information on the hazard and resulting risk from earthquakes is available at https://geology.utah.gov/hazards/earthquakes-faults/, from the Utah Seismic Safety Commission at https://ussc.utah.gov, and at the agency websites:

Geoscience and Utah
How does geoscience affect Utah?
The American Geosciences Institute (AGI) is currently releasing State Geoscience Information factsheets that show the role geoscience plays in powering our state’s economy. The Geoscience and Utah Factsheet highlights information from many Utah geoscience areas including, employment, water, minerals, energy and hazards.
Below is page 1 of the Utah factsheet showing an overview of the economic contributions that geology and geoscience bring to Utah.
AGI’s Geoscience Policy team created State Geoscience Information factsheets to inform geoscientists and decision makers on how geoscience impacts their state.
