Glacial Geology of the Northern Uinta Mountains
Glacial deposits on the north slope of the Uinta Mountains were investigated through map and air photo interpretation combined with fi eld mapping. Deposits representing the Smiths Fork (local Pinedale equivalent), Blacks Fork (Bull Lake equivalent) and pre-Blacks Fork Glaciations are present in the form of terminal and lateral moraines, ground moraine, and outwash valley trains. Nineteen separ...
متن کاملEquilibrium-line altitudes during the Last Glacial Maximum across the Brooks Range, Alaska
ABSTRACT: Equilibrium-line altitudes (ELAs) were estimated for 383 reconstructed glaciers across the Brooks Range, northern Alaska, to investigate their regional pattern during the Last Glacial Maximum (LGM). Glacier outlines were delimited based on published field mapping and the original interpretations of aerial photographs. Glacier margins were digitised from 1:63 360-scale maps into a geog...
متن کاملGlacial Geology of the Southern Uinta Mountains
It has been known for over a century that the Uinta Mountains contained numerous alpine glaciers during parts of the Quaternary Period, yet until recently, the glacial record on the south side of the range had received little scientifi c attention. Results of recent 1:24,000-scale fi eld mapping of surfi cial deposits in the southern Uinta Mountains indicate that glaciers in the southwestern an...
متن کاملEquilibrium-line altitudes of the Last Glacial Maximum for the Himalaya and Tibet: an assessment and evaluation of results
Contemporary equilibrium-line altitudes (ELAs) for glaciers in the high mountains of the Himalaya and Tibet have considerable variation because the region is influenced by two major climatic systems (the mid-latitude westerlies and the south Asian summer monsoon) and glaciers are subject to strong topographic controls. Reconstructions of past ELAs based on the former extent of glaciers are nume...
متن کاملInvestigating the spatial distribution of summit flats in the Uinta Mountains of northeastern Utah, USA
Isolated, laterally extensive, gently sloping surfaces known as summit flats are present at high elevations in many Laramide ranges, and are particularly well developed in the Uinta Mountains of northeastern Utah. To investigate the spatial distribution of these surfaces, and to consider possible controls on this pattern, a map of summit flats in the Uintas was developed from digital elevation ...
