To further explore the possible climatic relationship of Uinta Mountain glaciers and the lake, and to add to the glacial chronology of the Rocky Mountains, we assembled a range-wide chronology of latest Pleistocene terminal moraines based on seventy-four cosmogenic 10 Be surface-exposure ages from seven glacial valleys. New cosmogenic-exposure Cited by: ward. The core of these mountains is very old (Precam- brian Era) quartzite and the outcrops on the flanks are ancient (Paleozoic and Mesozoic Eras) I imestones, shales, and sandstones (Hintze , Moyle , Murphy gb). The Uinta Mountains were extensively glaciated in recent (Pleistocene Epoch, Quartenary Period, Cenozoic Era).

A detailed geology of the Uinta Mountains written at a level that the educated person can enjoy. Full of interested detail, but not over loaded with technical information. The only faults are all the photos are black and white and sometime difficult to interpret, and some labels on the illustrations are by: Were the Uinta Mountains completely covered in glaciers during the Pleistocene ice ages.

The eastern Uinta Mountains did not accumulate enough ice to form glaciers due to their lower elevation, but they were no doubt covered in Pleistocene Geology of the Uinta Mountains book much of each year. The western Uintas, on the other hand, did have thick ice and glaciers.

In the Uinta Basin at Towanta Flat, just south of the mountain front and just west of Lake Fork (fig. 63), local but clear-cut deformation occurred in late Pleistocene time.

A graben and several subordinate fault scarps more than 3 miles long displace what probably are Bull Lake age (late Pleistocene) glacial-outwash terraces, but the faults do not cut across younger terraces or moraines of Pinedale age.

The Nonglacial Surfi cial Geology of the Henrys Fork, Uinta Mountains, Utah and Wyoming Ron Counts*and Joel Pederson† ABSTRACT Surfi cial deposits below the glacial termini of the Henrys Fork drainage have been mapped atscale to develop a nonglacial Quaternary stratigraphic framework for the northeastern Uinta Mountains.

The opening of the West after the Civil War greatly stimulated early geologic exploration west of the th Meridian. One of the areas first studied, the Uinta Mountains region, gained wide attention as a result of the explorations of three Territorial Surveys, one headed by John Wesley Powell, one by Clarence King, and one by Ferdinand V.

The Uinta Basin (also known as the Uintah Basin) is a physiographic section of the larger Colorado Plateaus province, which in turn is part of the larger Intermontane Plateaus physiographic division.

It is also a geologic structural basin in eastern Utah, east of the Wasatch Mountains and south of the Uinta Uinta Basin is fed by creeks and rivers flowing south from the Uinta.

Glaciation, likely during the latest Pleistocene/early Holocene.

Two drainages also contain evidence for Neoglaciation in the late Holocene, but before the classic Little Ice Age.

The upper Bear River flows northward for ~ km from its headwaters in the northwestern Uinta Mountains, generally following the strike of regional Laramide and late Cenozoic structures.

These structures likely also control the flow paths of groundwater that feeds Bear Lake, and groundwater-fed streams are the largest source of water when the.

The Uinta Mountains are located in northeastern Utah. But, to understand how they came to be, one must look at the history of the region as a whole. Utah first emerged after the Hadean eon as a mass of metamorphosed rock, with the oldest found rock in Utah dating to.

His principal responsibility is to map the geology of 30′ x 60′ quadrangles that cover the Uinta Mountains and Uinta Basin. In addition to his mapping efforts in northeastern Utah, Doug has mapped quadrangles in the central Utah thrust belt.

GLACIATION OF THE UINTA MOUNTAINS On the flanks of the range the areas not covered by ice were between the great canyons. These areas became broader and broader to the north and south, beginning as narrow ridges near the crest-line (Fig.

The marine and fluvial metasedimentary rocks in the core of the Uinta Mountains are of Neoproterozoic age (between about million and million Peak: Kings Peak.The Uinta Basin lies south of the Uinta Mountains. The southern rim of the basin is formed by the Tavaputs Plateau of the Book Cliffs, and the western rim is formed by the Wasatch Mountains.

The central portion of the basin has an elevation of 5, to 5, feet. Asphalt Ridge divides the Utah portion of the Basin into two unequal parts.During the Pleistocene ice age, Utah’s climate cooled down and glaciers formed in the mountains. The Great Basin valleys had no outlet to the ocean, so they filled up with water.
