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.

This compilation includes 20 reports pertaining to U.S. Geological Survey (USGS)-funded National Earthquake Hazards Reduction Program (NEHRP) paleoseismic investigations conducted between 1978 and 2012, one report that predates the NEHRP program, and 36 annual to semi-annual Summaries of Technical Reports authored by funded NEHRP investigators. These reports contain information on some of the first paleoseismic investigations conducted on the Wasatch fault zone. Original authors made few copies of these reports, and many are very difficult to locate. This publication makes these otherwise hard-to-find legacy reports easily accessible to scientists, government policy makers, and the general public.

Residents and agencies are racing to fight debris and water flow caused by an unusually wet “monsoon season” in Utah that has caused slides and the threat of slides from Huntington to Alpine and across the Wasatch Front.

Prominent cliffs of gently dipping Mississippian-age Deseret (upper) and Gardison (lower) Limestone are exposed along the walls of Ogden Canyon. These strata are part of a thrust sheet emplaced during the Sevier orogeny, a regional mountain-building event that affected much of western Utah between about 140 and 50 million years ago.

Bureau of Land Management has rescheduled the presentation “Microbes, Mars & Moqui Marbles” on Tuesday, July 16. The program is a special Grand Staircase-Escalante National Monument (GSENM) Walks and Talks Lecture Series presentation to be held at the BLM Kanab Visitor Center, located at 745 East Hwy 89, in Kanab, Utah.
Beginning at 7 p.m., Dr. David Loope will reveal new insights into how microbes affect geology. Based on his recent research on the Navajo Sandstone within GSENM, Dr. Loope will explain how microbes, that have lived just below Earth’s surface for at least three billion years play an important part in the development of Moqui Marbles on Earth, as well as other planets, including Mars.

You wouldn’t know it from experience, but the Wasatch Front is one of the most seismically at risk areas in Utah and in the Intermountain West. Scientists are looking at thousands of years of earthquake history to learn more about the hazard we face. Kim Schuske has this story.
