A CTIVIT Y 13.4 Glacier National Park Investigation

Name: ______________________________________ Course/Section: ______________________ Date: ___________

Refer to the map of Glacier National Park in FIGURE 13.14 .

A. List the features of glaciation from FIGURES 13.3 , 13.4 , 13.8 , or 13.9 that are present in FIGURE 13.14 .

B. Locate Quartz Lake and Middle Quartz Lake in the southwest part of the map. Notice the Patrol Cabin located between these
lakes. Describe the chain of geologic/glacial events (steps) that led to formation of Quartz Lake, the valley of Quartz Lake, the
small piece of land on which the Patrol Cabin is located, and the cirque in which Rainbow Glacier is located today.

C. Based on your answers above, what kind of glaciation (mountain versus continental) has shaped this landscape?

D. Locate the Continental Divide and think of ways that it may be related to weather and climate in the region. Recall that
weather systems generally move across the United States from west to east.

1. Describe how modern glaciers of this region are distributed in relation to the Continental Divide.

2. Based on the distribution you observed, describe the weather/climate conditions that may exist on opposite sides of the
Continental Divide in this region.

2

E. Describe how the size (area in km ) of Agassiz Glacier changed from 1850 to 2005.

2
F. Describe how the size (area in km ) of Vulture Glacier changed from 1850 to 2005.

2
G. REFLECT & DISCUSS What do you expect the area (km ) of Agassiz and Vulture Glaciers to be in 2020? Explain.
