  1. How can you distinguish bedrock from glacial ice from unconsolidated moraine deposits on this topographic map?




  2. What glacial landform is the letter A pointing to? Justify your answer.




  3. What type of glacial landform is the letter B pointing to? Justify your answer.




  4. Describe the general appearance of the landform identified by the letter B; what would this landform look like if you could see it in person?




  5. How does the shape of the contour lines help define what the landform represented by letter B looks like?




  6. What type of landform do the letter C's represent?

  1. What type of glacier landform is identified by the letter A?



  2. What type of glacier landform is identified by the letter B?



  3. Approximately how many years of glacial flow is visible based on the features identified by the letter B? Explain.




  4. What type of landform does the letter C identify?

  1. The letter A is pointing to Avalanche Peak. What type of landform is Avalanche Peak? How did the shape and spacing of the contour lines help you determine the type of landform?



  2. The letter B refers to a landform that starts at Avalanche Peak and extends north-northeast to just past the letter B. What type of landform is this? How did the shape and spacing of the contour lines help you determine the type of landform?



  3. Letter C is sitting in a lake. What type of landform is this lake an example of?



  4. There are two well-defined cirques on this map. Draw a line identifying the location of the headwall to each of these cirques.



  5. Letter D is sitting in a valley. Draw a sketch of the shape of the valley from one side of the valley to the other side of the valley using the contour line spacing to help get the valley profile correct. Based on your sketch, was this valley most likely carved by a glacier or by the river that's currently flowing in the valley bottom? Explain.
Topographic Map: Mt. Jackson, CO

Identify the following features on the photo to the right:

  • two large cirques and one smaller cirque;
  • one horn;
  • one arete;
  • three cirque glaciers;
  • two valley glaciers;
  • one medial moraine; and,
  • glacial till that is not clearly definable as an end, a medial, or a lateral moraine.
