Name: ______________________________________ Course/Section: ______________________ Date: ___________

A. Refer to FIGURE 13.15 and fill in the Nisqually Glacier Data Chart below. To do this, use a ruler and the map’s bar scale to

measure the distance in kilometers from Nisqually River Bridge to the position of the glacier’s terminus (red dot) for each year
of the chart. Be sure to record your distance measurements to two decimal points (hundredths of km).
