A change to a warmer, drier climate beginning as early as 1900 was responsible
for triggering a dramatic, rapid retreat of Collier Glacier, Oregon, between 1924 and
1940. Although there was a dramatic decrease in precipitation contemporaneous with this observed "step-function" response of mass loss, it is unclear if climate...
Glaciers are effective reservoirs because they moderate variations in runoff and
supply reliable flow during drought periods. Thus, there needs to be a clear
understanding of the influence of glacier runoff at both the basin and catchment scale.
The objectives of this study were to quantify the late summer contributions...
Mountain glaciers are receding worldwide with numerous consequences including changing hydrology and geomorphology. This study focuses on changes in glacier area on Mt. Hood, Oregon and Mt. Rainier, Washington where damaging debris flows have occurred in glaciated basins. Landsat imagery is used to map debris-free ice on a decadal time...
