Ice Contact: Moraines

Objectives:

Study sediment individual processes as a way to understand the formation of landforms.

Resources:

Benn and Evans Sections 7.1-7.4 and 11.3, 11.4

Tasks:

To better understand the processes we should consider as many examples as possible.

1. Study several air photographs and decide which (of Lawson, Kruger, or thrust) most likely formed each moraine and select one for detail study.

2. Obtain enlargment of ice margin area with corresponding stereo images (Monday Lab).

3. On the enlargment delineate the moraines - both the individual ridge crests, and overall forms. Also map out any other landforms you can determine. Colored pencils may help here.

4. For the major features on your map find a) at least 4 images from the image data base that illustrate the processes operating in your example. and b) at least two figures in the reading of the the same processes.

5. Decide which processes (e.g.of Lawson, Kruger, or thrust) formed the dominate features you mapped.

Product:

Enlargment marked up with ice-contact features and labels pointing to the images and figures found in #4. Either pass in the paper copy and a one page explination or e-mail the image and report.
