In this in-class lab activity you will use your experience observing geology in the field to work with topographic and geologic maps (including cross-sections). We will also think about how constructing cross-sections helps us understand the history of geologic events.
The in-class activities will prepare you for this detailed cross-section that you will turn in at our next meeting. You might have time to start it during our meeting depending on how fast we progress.
Somewhere, Wyoming. For this example you will complete a detailed cross section long the indicated A-A' line. This will be turned in next week. Neatness, detail, use of colored pencils for units, etc., really count.
This map shows a couple of cross-sections that may be useful to study. It's not that these cross-sections are exactly like the ones on the Somewhere, Wyoming map, but rather that they show some general common structures. It will therefore help your visualization skills between a geologic map and a cross section.
We began discussing these in our lab meeting. Please finish/re-do these in a neat way. Here is a link to fresh blank copies if you need to print them out: three cross sections.
