Caption Comment: Wood and Smith state that "the glacier flows in a NE direction for ~10 km through a steep-walled valley…Over the last century the Saskatchewan Glacier has experienced significant downwasting and frontal retreat."
He attempted to reconcile the downwasting with this layer still being extant by hypothesizing a large precipitation event in the early 1960s.
Thompson has reported massive 20th century downwasting of the Kilimanjaro glacier – this seems unarguable.
