Prehistoric Timberline Adaptations in the Eastern Uinta Mountains, Utah
… archaeological site (3350 m) in the eastern Uinta Mountains, Utah, uncovered at least three ephemeral brush structures. These temporary timberline dwellings are the highest structures excavated in Utah to date. The periods of occupation range from the early Fremont period to the post-contact …

Influence of structural variability on glacially-eroded steps, Uinta Mountains, UT
… valleys on the southern slopes of the western Uinta Mountains exhibit stepped erosional profiles. These profiles consist of tall, steep, cliffs (~10m high) separated by low relief areas, which are often occupied by lakes. Directly opposite these valleys, on the northern slopes of the range, the …

Tectonics of the Uinta Recess in the Sevier Fold-Thrust Belt, Utah
… developed, rather than a tear. In sum, the Uinta recess reflects both variation in sedimentary basin thickness prior to the origin of the Sevier fold-thrust belt, and the affects of later (Laramide) uplift and Tertiary extension.

Contemporary seismicity and tectonics of the south flank of the Uinta Mountains, Utah
Includes bibliographical references.

A Uintan (Late Middle Eocene) Flora and Fauna from the Uinta Basin, Utah
… invertebrate, and vertebrae fossils from the Uinta Formation in the Uinta Basin, south of Myton, Utah, USA, provides evidence of environmental change. Paleobotanical specimens are preserved in late stage Uinta Lake sediments and coarse-grained fluvial sediments which are stratigraphically 650 …

Mapping and Kinematic Structural Analysis of the Deep Creek Fault Zone, South Flank of the Uinta Mountains, Near Vernal, Utah
The geology along the southern flank of the Uinta Mountains, located north of Vernal, Utah, has been mapped at the 7.5' scale within two quadrangles: the Dry Fork and Steinaker Reservoir Quadrangles. Ambiguities dealing with stratigraphy, structural geology, and geohazards are currently being …

Pre-Historic Landslides on the Southeast Flank of the Uinta Mountains, Utah: Character and Causes of Slope Failure
… been mapped along the southeast flank of the Uinta Mountains. Large landslide deposits are up to 4.6 kilometers long and have an area of approximately 5-9 km². Landslide types include multiple and successive rock slumps, debris slumps and debris flows. Most landslides have a main head scarp in …

Facies, stratigraphy, and mineralogy of the carbonate marker and D marker units, lower Green River Formation, Uinta Basin, Utah
… within the Lower Green River Formation in the Uinta basin. Both units were measured in a series of accessible canyons along the Roan Cliffs on the southern margin of the basin. This was accomplished by incorporating measured outcrop, petrographic analysis, X-ray fluorescence, X-ray diffraction, …

Analysis of faults and fractures, and their impact on a tight gas sand resource play in the Uinta Basin
Includes illustrations, maps.

Seismic and Well Log Attribute Analysis of the Jurassic Entrada/Curtis Interval Within the North Hill Creek 3D Seismic Survey, Uinta Basin, Utah, A Case History
3D seismic attribute analysis of the Jurassic Entrada/Curtis interval within the North Hill Creek (NHC) survey has been useful in delineating reservoir quality eolian-influenced dune complexes. Amplitude, average reflection strength and spectral decomposition appear to be most useful in locating …

Piecing Together the Triassic/Jurassic Stratigraphy Along the South Flank of the Uinta Mountains, Northeast Utah: A Stratigraphic Analysis of the Bell Springs Member of the Nugget Sandstone
… Jurassic strata along the south flank of the Uinta Mountains has been somewhat confusing because of the position of the study area between southern Wyoming, where one set of names is used, and central/southern Utah where a different set of formation names is used. The Nugget Sandstone or Glen …

Probabilistic source-to-sink analysis of the provenance of the California paleoriver: implications for the early Eocene paleogeography of western North America
… in the Roan Cliffs on the southern margin of the Uinta Basin, UT make up a genetically related lobate wedge of dominantly fluvial deposits. Estimates of the size of the river that deposited this wedge of sediment vary by more than an order of magnitude. Some authors suggest the sediments are …

Mammalian Postcranial Evolution and Primate Extinction in the Middle Eocene of North America
… parts of the Eocene: 55-46 ma). Beginning in the Uintan North American Land Mammal Age: 46-42 ma) primates declined in diversity and abundance in the Rocky Mountain region. This decline has been linked to the recession of tropical rain forests out of northern latitudes at that time. Climatic …
