Abstract

Different opinions on this question are implied in two contrasting models for deglaciation in the northeastern United States. One involving regional stagnation, assumes a sediment source in stagnant glacier ice| the other, involving stagnation zone retreat, considers active ice the principal sediment source. This paper presents reported values of debris content in glacier ice and uses these values to calculate theoretical sediment volumes for a small drainage basin (1 300 km) in northeastern USA. Comparison of calculated theoretical sediment volume with the estimated actual sediment volume in the basin indicates that active ice is probably the principal sediment source for melt water deposits.
