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...

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...

Mitochondrial DNA sequence data were used to examine the phylogeographic history of Steller's sea lions (Eumetopias jubatus) in relation to the presence of Plio-Pleistocene insular refugia. Cytochrome b and control region sequences from 336 Steller's sea lions reveal phylogenetic lineages associated with continental refugia south of the ice sheets in North America and Eurasia. Phylogenetic anal...

Introduction Glacial erratic boulders are plucked from bedrock by flowing ice, transported in the direction of ice flow, and deposited at the terminus of the glacier. If derived from a localized, distinctive region of bedrock, glacial erratics may be used as indicator stones to map the direction of ice flow. Furthermore, glacial erratics evolve during transport, becoming smaller and more rounde...
