Describe any visible differences in the amount of ice in the zones of accumulation and wastage in 1983 relative to 1955

What will be an ideal response?


The toe of the glacier has receded considerably between 1955 and 1983, indicating loss of ice from the zone of wastage. Within the zone of accumulation, about the same amount of rock is exposed along the glacier edges in the background of both photos, which suggests little if any change in the zone of accumulation.
