Exercise 6A:  Making a Geologic Map of SP Crater -- Your instructor will demonstrate how you would make a geologic map of SP Crater, north of Flagstaff in northern Arizona.  The image and QTVR movie below will let you see the area in detail for yourself.  You do not have to do anything with these.

aztm_sp_3dcrop.jpg (23521 bytes) QuickTime VR movie of satellite image draped over topography for a slightly larger area than shown in the image above. The file is large (7 Mb), so give it time to load.

Exercise 6B:  Mapping the Geology of Painted Canyon -- To construct a geologic map of Painted Canyon and reconstruct the geologic history, use the resources listed below.  Especially useful in starting the geologic map will be the first three images, which label key places to begin drawing the boundaries (contacts) between different rock units. Then, view the overviews (especially those with bumps removed) and panoramas to extend your contacts away from the key places. Save the aerial photograph for last, but be sure to view it too.

Exercise 6C:  Showing the Rock Units Beneath the Surface -- To help visualize the geometry and thickness of rock units beneath the surface, check out these cross sections.
