Glacier lab imagery part II

Glacial geomorphology, part II

Topographic maps

This GigaPan is the basis for the questions about topographic maps in the second part of the lab. If any of the images don’t load up at first and appear as black rectangles, try clicking the “refresh” button in the upper right corner of the embedded GigaPan.
It looks like this:

It may also be useful to examine these same sites in a seamless Google Map “terrain view” of the North American landscape (note the drop-down menu in the upper left corner):


Continental glaciation in LiDAR

The final set of questions for the lab deal with a LiDAR image of Scandanavia. This map shows several excellent examples of glacial geomorphology. LiDAR is a super-high-precision topographic mapping technique that uses lasers on aircraft to figure out exactly how high the land surface is. This LiDAR has been color-coded to show elevation: blue is low (but not sea-level); and the colors grade upward from green to yellow to orange to white (highest).

Identify one of each of the following (take a screen shot of an example of each, and submit those 5 images with your lab, labeling key features of the image):

  • glacial striations
  • terminal moraine
  • outwash delta
  • esker
  • kettles
