This data set, when used in conjunction with the phenomena resource, Melting Glaciers, would allow students to investigate the question:
How has the rate of glacial area changed in the past 50 years?
The data set contains the measurements in square meters of 37 named glaciers located in Glacier National Park and Flathead National Forest. The measurements were derived from aerial photography and satellite imagery. Students can explore rates of change over several decades as measurements were taken in 1966, 1998, 2005, and 2015. Teachers can have students analyze and make comparisons to show if glacial melt is occurring at a faster rate now than it did in the past.
