My view: Radon, the unrecognized killer

deseretnews.com

We Utahns are fortunate to live in a state surrounded by natural splendor with peaks of granite, fertile flat lands and bountiful deserts, but within this natural beauty lurks a natural (but avoidable) killer, radon. Radon is a radioactive gas that is silent, colorless, tasteless, odorless and carcinogenic.

Geologic Map of The Donkey Flat Quadrangle, Uintah County, Utah

By: Paul H. Jensen, Douglas A. Sprinkel, Bart J. Kowallis, and Kent D. Brown

The Donkey Flat quadrangle is less than 10 miles north-northeast of Vernal, Utah, along the south flank of the Uinta Mountains in Uintah County. It includes Red Fleet State Park and is crossed by U.S. Highway 191 (a National Scenic Byway). The geology is well exposed and uncomplicated, making a dramatic landscape with thick sandstone cliffs and varicolored to drab gray slopes. The quadrangle’s namesake, Donkey Flat, is a one of several geomorphic surfaces mantled by piedmont gravel deposits.

Landslide Inventory Map of The Sixmile Canyon and North Hollow Area, Sanpete County, Utah

By: Gregg S. Beukelman, Ben A. Erickson, and Richard E. Giraud

This map represents a landslide inventory of part of the Sixmile Canyon and North Hollow area, Sanpete County, Utah, at a scale of 1:24,000. The map covers 42 square miles on the west side of the Wasatch Plateau and includes parts of the Sixmile Creek and North Hollow-Twelvemile Creek Hydrologic Units. The map and accompanying geodatabase show and characterize landslides and provide information useful for managing landslide-related issues. Spatial and tabular data for each landslide are stored in the geodatabase and linked to the inventory map. Landslide information in the geodatabase includes: area, material type, movement type, landslide deposit name, landslide source name, movement activity, thickness, movement direction, approximate movement, dates, geologic unit(s) associated with landsliding, confidence in mapped boundaries, mapper, peer reviewer, and general comments. This CD contains geographic information system (GIS) files in ESRI file geodatabase and shapefile formats. Specialized GIS software is required to use the GIS files.

POTD February 2, 2016: Mount Timpanogos, Wasatch Range, Utah County, Utah

Happy Groundhog Day, everyone! This photo feels as warm as Milltown Mel’s early spring prediction (compared to this morning in Salt Lake at least, brr!). What’s everyone hoping for?

Utah Geological Survey Releases New Interactive Fault Map

geology.utah.gov

The Utah Geological Survey (UGS) has made the Utah Quaternary Fault and Fold Database available through a new interactive web application on the UGS website. This database contains information on faults and fault-related folds considered to be potential earthquake sources. The faults and folds in the database are considered to have been sources of large earthquakes (about magnitude 6.5 or greater) during the Quaternary geologic time period (past 2.6 million years); these geologic structures are the most likely sources of large earthquakes in the future. The Utah Quaternary Fault and Fold Database is the primary source of Utah data for the Quaternary Fault and Fold Database of the United States maintained by the U.S. Geological Survey (USGS).

The interactive map’s user interface was built using ESRI’s JavaScript API. Several search options allow the user to locate a fault of interest, or specify a location to see if any Quaternary faults are nearby. Pop-up windows provide a brief summary of important information associated with the faults, as well as a link to detailed reports available through the USGS national database. Users can select from a variety of basemaps including topographic, shaded relief, and satellite imagery. A glossary explains terms used in the pop-up windows as well as terms used in the detailed reports that may be unfamiliar to non-geologists.

In addition to the UGS interactive map, the Utah Quaternary Fault and Fold Database exists as a fully attributed GIS feature class in the State Geographic Information Database, and can be downloaded from the AGRC at http://gis.utah.gov/data/geoscience/quaternary-faults.
