1. Geologic Mapping Science Olympiad Trial Event 2011 Amanda Baker

2. Geology: The Field -vs- The Lab Table Can’t take all students into the field … but we can reproduce important aspects of the experience Decision Making Use of Tools Defense of Interpretations Time Management

3. What does it take to implement these four things? Decision Making Use of Tools Defense of Interpretations Time Management Geologic time scale Relative and absolute age dating Depositional environments Field measurements Folding and Faulting Strong Background Knowledge Plate Tectonics Rock formation Lat/long, UTM Map projections Topographic maps Developing a Set of Tools Provide data Interpret data Data - vs - Interpretations

4. Strong Background Knowledge Plate Tectonics Rock formation Lat/long, UTM Map projections Geologic time scale Relative and absolute age dating Depositional environments Field measurements Folding and Faulting Topographic maps Develop a Set of Tools Provide data Interpret data Data - vs - Interpretations

5. What does this mean for exam questions? Knowledge-Based Multiple choice Short answer Diagrams Tasks Application Interpretation Integration of multiple data sets Interpretation Tasks Higher-level application of tools and data sets More

6. Knowledge-Based What is the contour interval? Of points I, E, G, and D, which is at the greatest and least risk for flooding? Why? If a spring were sourced at the red dots, draw the path the water would take.

7. Tasks Draw a topographic profile from A to E. A bed outcrops at points B, J, and D. Determine the strike and dip of the bed. If the “Photo” was taken facing west, draw a dot where the photographer was likely standing. Why there? N

8. Interpretation Tasks Using an equal area stereonet, find the strike and dip of a bed with the apparent dips (036, 25E) and (197, 65E).

9. Interpretation Tasks Describe the type of feature depicted in the stereonet plot in detail Is this feature likely to be the result of one, multiple, or a progression of deformation events?

10. Interpretation Tasks Complete the block diagram and label any major features

11. Interpretation Tasks Draw a cross-section from A to A’ On your cross-section, label the areas of greatest and least confidence and explain A A’

12. What is a Cross Section?

13. Multiple Styles of Cross-Sections
