Hydrometeorology, Suspended Sediment and Conductivity in a Large Glacierized Basin, Slims River, Yukon Territory, Canada (1993-94)
The Slims River was monitored for global solar radiation, air temperature, discharge, suspended sediment, and dissolved load in 1993 and 1994. Peak seasonal discharge occurred late in the summer and reflects a typical glacierized basin hydrograph, with increased bare ice surfaces contributing strongly to discharge in July and August. Air temperature, rather than global solar radiation, was most strongly correlated with discharge in both years, bu…
Ice‐dammed Lake History, Dusty Glacier, St. Elias Mountains, Yukon
Glacier margin ice‐dammed lakes have been a common feature of the glacial landscape of the St. Elias Mountains of the southwest Yukon. The sedimentary successions in the lake basins contain a record of glacier hydrology variability and ice‐dammed lake fluctuations. The interpretation of the sedimentology depends on an understanding of glacierized basin hydrology and particularly the suspended sediment dynamics of glacier discharge streams. A basi…
Glaciation in Alaska
Rock Glaciers, Southwest Yukon
Two distinct types of rock glaciers occur in southwest Yukon. One results directly from glaciation, with the production of abundant debris over glacier ice. The other forms during and after deglaciation, when instabilities develop in deposits and when ice included in these deposits responds to climatic change
Rock Glacier Formation by High-Magnitude Low-Frequency Slope Processes in the Southwest Yukon
In the southwest Yukon, valley walls mantled by talus and glacial deposits have been modified by a variety of catastrophic processes. Avalanches, landslides, mudflows, and retrogressive slope failures have been triggered by a variety of internal and external causes. These flow mechanisms produce a range of landforms in the paraglacial environment that dominate the landscape, particularly in the higher mountain zones. Models of rock glacier format…
Mass Movement Processes in Metalline Creek, Southwest Yukon Territory
In Metalline Creek, a small valley in the Kluane Range of the southwest Yukon Territory, the glacial deposits and the talus material have been affected by mass movement processes promoted by the occurrence of glacier ice and ice formed from avalanche snow. In addition, minor periglacial mass movement processes occur in the valley. Variations in the type of process are attributed to altitudinal changes, to aspect, and to change in the height of th…
A Possible Advanced Hypsithermal Position of the Donjek Glacier
The history of the [Donjek] glacier from 1935 to the present is well documented photographically .... Documentation of the Hypsithermal and Wisconsin history of the glacier is less abundant. ... During the summer of 1970 the terminus area of the Donjek Glacier and the lower part of the glacier valley were investigated for evidence of its Hypsithermal position. No evidence was found in the valley occupied by the glacier to indicate that it had ret…
