GEOLOGIC MAPPING IN GOOGLE EARTH: TOOLS AND CHALLENGES
This activity has benefited from input from faculty educators beyond the author through a review and suggestion process. This review took place as a part of a faculty professional development workshop where groups of faculty reviewed each others' activities and offered feedback and ideas for improvements. To learn more about the process On the Cutting Edge uses for activity review, see http://serc.carleton.edu/NAGTWorkshops/review.html.

The Structural Geology Mapping Challenge is a web based Google Earth exercise, where students outline bedding traces and measure strike and dip orientations to determine fold geometry. Students start with predetermined training locations, where their answers are automatically graded. Once training is done, students determine a fold axis by fitting a great circle to the bedding poles on an inset stereographic net. Students also fit an axial plane to the fold. More advanced features are in development.
Create a fully-featured geologic map with ornamented / annotated lines and color-coded units using our web-based Google Earth tool using and outcrop data gathered in the field.
Skills and concepts that students must have mastered
Structural concepts, such as characterizing fold geometries, trend & plunge, axial plane orientation; stereonets
Basic stratigraphic concepts (superposition, original horizontality, etc.), basic field mapping concepts, basic elements of geologic maps
