| Abstract | (unpublished)
The map shows the location of glaciers and ice caps and also indicates the rivers and the lakes, which are fed by a glacier (or an ice cap) meltwater. The purpose of this plate
is to identify those streams which are fed by glacier meltwaters. Because of the scale of the map, many minor glaciers have not been shown and, hence, streams fed by such glaciers are not depicted as being glacier fed. The proportion of
glacier-derived to non-glacier-derived water decreases as one goes downstream from the glaciers. The map shows many short streams in the Arctic islands and in the mountains of western Canada which are affected by glacier melt. However, the lower
reaches of long glacier-fed streams, such as the Mackenzie and Columbia Rivers, are affected very little by the presence of glaciers within their catchments.The 20th century has witnessed the shrinking of many glaciers. The release of this water from
storage has produced higher discharges from many glacier-fed streams than would be expected from precip |
