The characteristics of superglacial sediments, suspended stream sediments, and meltwater from ten Alaskan valley glaciers were determined. The glaciers are eroding five different types of bedrock. Superglacial sediments from six glaciers are relatively unmodified, but supergalcial sediment from the other four glaciers are mixtures of relatively unmodified glacial sediments and proglacial sediments. Mud is the major component of suspended stream sediments. These sediments are generally poorly sorted and contain distinct size modes. Mean grain size of suspended sediments is a function of glacial stream velocity. Mean Na, K, Ca, Mg, and Si concentrations in the meltwater streams ranged from 9.3 to 37 ppm. (Author)
