MODEL WIND ORDINANCE

Senate Joint Resolution 1 of the 2009 Utah Legislative Session tasked the Utah State Energy Program with developing a model wind ordinance. This was accomplished by way of the Utah Wind Working Group and input from stakeholders. The Model Wind Ordinance document incorporates comments from:

private citizens,
PacifiCorp,
City of Monticello,
Utah Clean Energy,
Iron County,
Utah League of Cities and Towns,
the Utah Wind Working Group
Salt Lake City Corporation, and
the Utah Division of Wildlife.

COMMUNITY VELOCITY MODEL (CVM) AND OTHER GEOPHYSICAL DATA

The Utah Geological Survey (UGS) and U.S. Geological Survey (USGS) have a cooperative agreement to study earthquake-hazards in Utah with an ultimate goal of producing detailed earthquake-hazards maps, including large-scale ground-shaking maps along the densely populated Wasatch Front urban corridor.

An important component of the ground-shaking maps is developing a three-dimensional model of the subsurface, a Wasatch Front Community Velocity Model (CVM), that incorporates shallow shear-wave velocity (Vs), deep-basin structure, and other effects. To aid in producing these maps, the UGS has compiled databases of Vs and deep-basin geophysical and well logs.

GEOLOGIC MAP OF THE ST. GEORGE AND EAST PART OF THE CLOVER MOUNTAINS 30′ x 60′ QUADRANGLES, WASHINGTON AND IRON COUNTIES, UTAH
Robert F. Biek, Peter D. Rowley, Janice M. Hayden, David B. Hacker, Grant C. Willis, Lehi F. Hintze, R. Ernest Anderson, and Kent D. Brown

A just-released map presents southwestern Utah’s geology in unprecedented detail. There is also an innovative 3-D version of the map and a virtual field trip for online viewing. The Utah Geological Survey (UGS) created all versions of the map.

The new geologic map covers 2000 square miles of southwest Utah. It stretches from Zion National Park on the east, through the St. George area, to the Beaver Dam and Bull Valley Mountains on the west, and from the Arizona border north through the Pine Valley Mountains.

MISCELLANEOUS PUBLICATION 09-4DM

GLACIAL GEOLOGIC MAP OF THE UINTA MOUNTAINS AREA, UTAH AND WYOMING
Jeffrey S. Munroe and Benjamin J.C. Laabs

This dataset represents the first complete inventory of the glacial deposits in the Uinta Mountains since Atwood (1909) described the glacial geology of this area. It is the result of previous and continuing work by the authors and others to better understand the glacial and climatic history of this fascinating area. It depicts the distribution of glacial deposits and post-glacial sediments including mass wasting, lacustrine, and rock glacier deposits. A discussion of the glacial history and a figure showing a reconstruction of the ice extent during the local Last Glacial Maximum are also included.

This DVD contains the geologic map at 1:100,000 scale in PDF format and an ArcMap 9.3 map document. Geographic Information System (GIS) files are provided in an ESRI file geodatabase and as ESRI shapefiles. Metadata, PDF, HTML, text, and image files are included to help the user view, evaluate, and use the spatial data.

A CLOSE CALL IN ROCKVILLE

The Utah Geological Survey (UGS) was notified of a large rock fall in Rockville, Utah Wednesday morning that damaged several buildings.  Geologists say it could have been much worse and are worried about the possibility of second boulder breaking loose.

Around 7:30 a.m., a boulder estimated to be 35-feet by 30-feet by 30-feet broke loose and rolled down a hill toward the home that Tamara Burton was renting.

Tyler Knudsen and Bob Blackett, UGS geologists, were asked by Rockville Mayor Alan Brown to investigate what happened.  According to air photos, the boulder had been there for at least four years after detaching from a ledge and sliding about 20 feet and coming to a rest on a 45-degree slope above Burton’s home.

LANDSLIDE STATUS STIRS DEBATE

The Spectrum

Hours of debate regarding the Green Hollow Landslide and the proposed Capo Di Monte subdivision on Cedar Mountain took place at the Iron County Planning Commission meeting Thursday, with no decisions made as of press time.

At the meeting the commission heard the recommendation of Utah Geological Survey Geologist Bill Lund.

Lund recommended that further study by expert engineers take place before further development be allowed to continue on one of the largest landslides in the state. The study will determine whether more development and water saturation in the area could cause the landslide to reactivate.

Lund also told the planning commission that several smaller landslides on the mountain had been activated since the Cedar Highlands subdivision was completed. Conclusions were based on the original studies in 1981, which stated that the landslide was inactive.

PUNY FOSSIL FIND IS BIG TO SCIENCE

Salt Lake Tribune

Jeff and Denise Roberts love to roam the hills south of Richfield, sleuthing for fossils and ancient artifacts. During one of those trips several years ago, the couple found fossilized jaw bones so small they can sit on a penny.
The significance of those puny jaws outweighs their size: Paleontologists say they shed light on an era in Utah 8 million years ago that has produced few fossils, unlike the huge dinosaur bones from earlier periods that have made the state a paleontology treasure trove.
The Roberts reported their find to state experts, who determined the fossils came from two heretofore unknown species of rodents related to modern deer and pocket mice. In their honor, the species related to the deer mouse was named Basirepomys robertsi , while the other species was named Metaliomys sevierensis for the formation in Sevier County where the fossils were found.

Glad You Asked—What should you do if you find a fossil? Can you keep it? Should you report it?

Carole McCalla and Sandy Eldredge

Fossils – remains, traces, or imprints of past plant and animal life – are widely found throughout Utah. Depending on land ownership, some fossils can be collected for personal non-commercial use.

However, vertebrate fossils (see description below) may not be collected on any federal or state lands.

Whether you can keep a fossil or not depends on
1. the type of fossil, and
2. who owns or manages the land where the fossil was found.

MAP 238

GEOLOGIC MAP OF THE GRANITE PEAK AND SAPPHIRE MOUNTAIN AREA, U.S. ARMY DUGWAY PROVING GROUND, TOOELE COUNTY, UTAH
Donald L. Clark, Robert F. Biek, Grant C. Willis, Kent D. Brown, Paul A. Kuehne, J. Buck Ehler, and Carl L. Ege

This area is located in west-central Utah within the eastern Basin and Range Province, near the southern margin of the Great Salt Lake Desert, and within the confines of Dugway Proving Ground.  Granite Peak consists of a granitic intrusion that is Late Jurassic in age (149 million years old).  The upper part of the intrusion was altered and intruded by numerous pegmatite dikes.  Metamorphic rocks of likely Paleozoic or Proterozoic protoliths are exposed at the far south end of the mountain.  These granitic and metamorphic rocks were exhumed during Basin and Range extension, likely from about 15 to 5 million years ago.  Sapphire Mountain is a Miocene-age rhyolite flow that erupted 8 million years ago.  Quaternary surficial map units include lacustrine, alluvial, and eolian deposits, and desert mudflats.  Three of the four primary shorelines of the Bonneville lake cycle are preserved on the mountains’ flanks.

Utah is making a multi-million dollar investment in residential energy efficiency. The Utah State Energy Program (USEP) has issued a Request for Grant Applications (RGA) for a Home Performance with ENERGY STAR program. Home Performance with ENERGY STAR offers a comprehensive approach to improving energy efficiency in existing homes.

USEP will award up to $4.5 Million for this program. The Home Performance with ENERGY STAR program will include activities such as:

  • establishing market baselines and performance indicators,
  • contractor training opportunities,
  • homeowner outreach,
  • home performance assessments and a utility bill analysis,
  • projected cost-effectiveness of energy retrofits,
  • installation of energy efficiency measures, and
