Glacial Budgets

This resource is aimed at 'A' Level students studying glaciation. It enables them to use a range of data for the South Cascades Glacier in Washington State, USA to support picture evidence on the retreat of the South Cascades Glacier. Students are asked to calculate the net glacial budget of the glacier for each year of a 21 year period. This data can then be graphed and students use the graph to describe the changes that have taken place in the glacier over this period and draw conclusions as to whether this supports the photographic evidence.
